Question

What is the least common multiple of $5$ and $7$?

Answer 1

Let us calculate the lowest common multiple of two numbers as follows:

$L.C.M(a,b)=\frac{a\times b}{gcd(a,b)}$

Where, LCM represented as Least common multiple and

GCD represented as Greatest common denominator.

Hence, $5$ and $7$ are the prime numbers (no denominators other than one and themselves), one is their greatest common denominator.

Therefore, $35$ is the least common multiple of the numbers $5$ and $7$.
