240 divided by 7 does not give a whole number and therefore 240 is not a multiple of 7.
To find the Lowest Common Multiple (LCM) of two numbers, you need to determine the smallest number that is a multiple of both numbers. To find the LCM of 90 and 240, you first need to find the prime factorization of each number: 90 = 2 x 3^2 x 5 and 240 = 2^4 x 3 x 5. Then, you take the highest power of each prime factor that appears in either number: LCM = 2^4 x 3^2 x 5 = 720. Therefore, the LCM of 90 and 240 is 720.
It's not. It's a factor.
240 because... 6 x 40 = 240 4 x 60 = 240
