The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both numbers. To find the two numbers with an LCM of 1260, we need to factorize 1260 into its prime factors, which are 2, 2, 3, 3, 5, and 7. We then pair these prime factors to form two numbers, such as 2 x 2 x 3 x 5 = 60 and 3 x 7 = 21. Therefore, the two numbers with an LCM of 1260 are 60 and 21.

You can find the GCF of two numbers by dividing their product by their LCM. The LCM of 30 and 42 is 210. What is their GCF? 30 x 42 = 1260 divided by 210 = 6 The GCF of 30 and 42 is 6.
The LCM is 900.
The LCM is 1260. The GCF is 12.
The LCM of two numbers is one of the numbers when one of the numbers is a multiple of the other. The LCM of two numbers is the product of the numbers when they are relatively prime. In all other cases (like consecutive even numbers that aren't 2 and 4) the LCM is as you describe.
Two or more numbers are needed to find their LCM
