What is the LCM of 4 and 7 using continuous division?

The LCM of 4 and 7 is the product of all prime numbers on the left, i.e. LCM(4, 7) by division method = 2 × 2 × 7 = 28.

Which number is a common multiple of 7 and 4?

Multiples of 4 = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40,.. Multiples of 7 = 7, 14, 21, 28, 35, 42, 49, 56, 63, 70,… We can see the common multiple of 4 and 7, from the above-given multiples is 28. Therefore, 28 is the least common multiple of 4 and 7.

What is the LCD of 4 7?

4: 4,8,12,16,20,24,28,32,36,40,44,48,52,56... 7: 7,14,21,28,35,42,49,56,63,70,77... Then you find the first number which 4 and 7 have in common. 4 and 7 have 28 and 56 in common BUT the LCM would be 28 since that's the LEAST common, or the smallest number that they would have in common.

Why do we use factor trees?

Factor trees are a way of expressing the factors of a number, specifically the prime factorization of a number. Each branch in the tree is split into factors. Once the factor at the end of the branch is a prime number, the only two factors are itself and one so the branch stops and we circle the number.
