Well, let's paint a happy little picture with prime numbers! To find the Least Common Multiple (LCM) of 12, 28, and 40, we first break down each number into its prime factors: 12 = 2^2 * 3, 28 = 2^2 * 7, and 40 = 2^3 * 5. Then, we take the highest power of each prime factor that appears in any of the numbers, which gives us 2^3 * 3 * 5 * 7 = 840. So, the LCM of 12, 28, and 40 using prime numbers is 840.
Oh, dude, the LCM of 12, 28, and 40 using prime numbers is like the smallest number that all three of those numbers can divide into evenly. So, you break down each number into its prime factors, which are like the building blocks of numbers, and then you just pick the highest power of each prime factor that appears in any of the numbers. In this case, the LCM would be 2^3 * 3 * 5 * 7, which is 840.
The least common multiple is the smallest number that is multiple of two or more numbers. 10: 10, 20, 30, 40, 50, 60 12: 12, 24, 36, 48, 60 15: 15, 30, 45, 60 The LCM of 10, 12 and 15 is 60. ------------------------------------------ Using prime factorisation: prime factorise each number in power format: 10 = 2 x 5 12 = 2² x 3 15 = 3 x 5 LCM is the product of the highest power of every prime that appears in any of the numbers (across the numbers): lcm = 2² x 3 x 5 = 60
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
The numbers are: 12 and 72
The least common multiple of 12 and 16 is 48The prime factorization of 12 is 2 x 2 x 3The prime factorization of 16 is 2 x 2 x 2 x 2The LCM of 16,12 is: 2 x 2 x 2 x 2 x 3 = 4848The Least Common Multiple (LCM) for 12 16 is 48.
LCM is 120, which is the multiple of the highest power of prime factors in the given numbers (2^3 x 3 x 5).Least Common Multiple (LCM) for 12 40 is 120
The LCM of the given two numbers is 48
Two or more numbers are normally needed to find the LCM
It is: 60
2x2x3 = 12
2 x 2 = 4 2 x 3 = 6 2 x 2 x 3 = 12, the LCM
If the GCF of two numbers is 1, their LCM will be their product. Such numbers are called relatively prime, or co-prime. Any two prime numbers (like 3 and 5) will be that way, but the numbers don't have to be prime (like 4 and 9).
It is 84 by multiplying both numbers because 7 is a prime and the prime factors of 12 are 2*2*3
If it's the lowest Common Multiple (LCM) of 12, 20, 24 and 32 that you're after, I think it's 480 (but my maths is a little rusty)
2 x 2 x 2 = 8 2 x 2 x 3 = 12 2 x 2 x 2 x 3 = 24, the LCM
They are: 12 and 360 respectively
The prime factors of 8 are 23 and the prime factors of 12 are 22 x 3. Since the LCM of two or more given numbers is the product of the largest power of each prime factor in the given numbers, then the LCM of 8 and 12 is 24 (23 x 3).
LCM is 120, which is the multiple of the highest power of each prime in the given numbers (23 x 3 x 5).
