Question

What is the least number that is divisible by 2,3,4,5 and 7? Explain your reasoning,

Answer 1

Prime factorization is unique....

Answer 2

2,3,4,5 and 7 are prime numbers with the exception of 4 which is 2 times 2.
The product you seek must be divisible by 2, 3, 2*2, 5 and 7.
The factors of that number have to be 3, 2, 2, 5, and 7. Because 2 is a factor of 4, a third 2 is not required.

3*2*2*5*7 = ? Crank out that product for the answer.
