What is the LCM of 28 and 21?
To determine the least common multiple of two numbers, determine the prime factors of both number. Then, determine the prime factors they have in common. Multiply all their prime factors together (in other words, multiply both numbers together) and divide by the prime factors they have in common (in other words, their greatest common factor). The prime factors of 21 are 3 and 7. The prime factors of 28 are 2, 2, and 7. The prime factors in common are a single 7. Therefore, the lowest common multiple is 21 x 28 ÷ 7 = 84
What is the least common multiple of 9 and 12?
The LCM of 9 and 12 is: 36To determine the least common multiple of two numbers, determine the prime factors of both numbers. Then, determine the prime factors they have in common. Multiply all their prime factors together (in other words, multiply both numbers together) and divide by the prime factors they have in common (in other words, their greatest common factor).The prime factors of 9 are 3 and 3.The prime factors of 12 are 2, 2, and 3.The prime factors in common are a single 3, the greatest common factor is 3.36: 4 x 9, 3 x 12.The least common multiple of 12 , 9 = 36.3636
Why is 198 the least common multiple of 99 and 18?
Prime factors of 99 in exponents: 32 and 11 Prime factors of 18 in exponents: 2 and 32 Mutiply all the highest prime factors: 2*32*11 = 198 which is the least common multiple of 99 and 18
What is the least common multiple of 14 and 42?
The LCM of 14 and 42 is 42. The simplest method to determine the least common multiple in this case is to notice that 42 is a multiple of 14. Since 42 is a multiple of 14, the least common multiple is 42. To determine the least common multiple of two numbers, you can also determine the prime factors of both numbers. Then, determine the prime factors they have in common. Multiply all their prime factors together (in other words, multiply both numbers together) and divide by the prime factors they have in common (in other words, their greatest common factor). The prime factors of 14 are 2 and 7. The prime factors of 42 are 2, 3, and 7. The greatest common factor of 14 and 42 is 14. So, the least common multiple of 14 and 42 is (2x7) x (2x3x7) ÷ 14 = 42.
What is the least common multiple for 686 and 365?
The least common multiple (lcm) of two or more numbers is the product of all prime factors of the numbers to their highest powers.The prime factors of 686 are 2 and 73The prime factors of 365 are 5 and 73.The least common multiple of 686 and 365 is 250390 (2 x 5 x 73 x 73).
What is the least common multiple of 65 and 92?
To find the least common multiple of two numbers you first need to split them into their prime factors: 65 = 5x13 92 = 2x2x23 The next step would be to identify any common prime factors, but in this case there are none, so we simply take all the prime factors and multiply them together: 5x13x2x2x23 = 5,980 Thus the least common multiple of 65 and 92 is 5,980.
What is the least common multiple of 2 3 5 and 9?
To determine the least common multiple of more than two numbers, determine the prime factors of all numbers. Then, determine the prime factors they have in common with at least one of the other numbers and the ones that are not in common. The prime factor of 2 is 2. The prime factor of 3 is 3. The prime factor of 5 is 5. The prime factors of 9 are 3 and 3. The prime factor 3 is a factor in common in one pair. Multiply all the factors together and divide by any that were in common with the other numbers. Therefore, the least common multiple is 2 x 3 x 5 x 9 ÷ 3 = 90
What are the factors and prime factors of 30600?
Prime Factorization: 2,2,2,3,3,5,5,17 The factors are all multiple combinations of these numbers.
What is the least common multiple of 24 and 32?
The LCM of 24 and 32 is 96. To determine the least common multiple of two numbers, determine the prime factors of both numbers. Then, determine the prime factors they have in common. Multiply all their prime factors together (in other words, multiply both numbers together) and divide by the prime factors they have in common (in other words, their greatest common factor). The prime factors of 24 are 2, 2, 2, and 3. The prime factors of 32 are 2, 2, 2, 2, and 2. The prime factors in common are 2, 2, and 2, so the greatest common factor is 2 x 2 x 2 = 8. The least common multiple or least common denominator is 24 x 32 ÷ 8 = 96.
What are all the common prime factors?
There are infinitely many prime factors.
What is the least common multiple of 51 and 77?
The first step to finding the least common multiple is to split the numbers into their prime factors. In this case: 51=3x17 77=7x11 The next step would be to identify any common factors. There are none, and so we simply take all the prime factors and multiply them together: 3x17x7x11 = 3,927 Thus the least common multiple of 51 and 77 is 3,927.
