The factors of 15 are 1, 3, 5, and 15. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The factors they have in common are 1 and 3. Therefore, the greatest common factor is 3. The greatest common factor can also be determined from the prime factors. The prime factors of 15 are 3 and 5. The prime factors of 24 are 2, 2, 2, and 3. The prime factors they have in common are a single 3, so the greatest common factor is 3.
24 = 23 x 31
24 x 32 x 5
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.
To work this out, you need to write the numbers as the product of their prime factors: 24 = 2x2x2x3 64 = 2x2x2x2x2x2 The next step is to identify any common prime factors. In this case both numbers have three 2s as prime factors. Multiply these together and you get: 2x2x2 = 8 Thus the HCF of 24 and 64 is 8.
As a product of its prime factors in exponents: 24*34 = 1296
It is: 23*3 = 24
As a product of its prime factors in exponents: 24*54 = 10,000
The common prime factors are 2 and 3.
As a product of its prime factors: 2*2*2*3 = 24
As a product of its prime factors in exponents: 24*56 = 250,000
Since 12 is a factor of 24, all of its factors, prime or otherwise, are common.
The factors of 15 are 1, 3, 5, and 15. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The factors they have in common are 1 and 3. Therefore, the greatest common factor is 3. The greatest common factor can also be determined from the prime factors. The prime factors of 15 are 3 and 5. The prime factors of 24 are 2, 2, 2, and 3. The prime factors they have in common are a single 3, so the greatest common factor is 3.
24 = 23 x 31
In prime numbers 19+5 = 24 or as a product of its prime factors 2*2*2*3 = 24
24 *3
144 = 24 x 32
