Answer 1

Question

WHAT IS THE LEAST NUMBER THAT IS DIVISIBLE BY 5, 6 AND 15?

Answer

Solution:-

The required no.= The LCM of the given numbers

The prime factorization of :

5 = 5 × 1

6 = 2 ×3

15 = 5 × 3

L. C. M = 3 × 5 × 2

The L.C.M of the given numbers 30.

Therefore The least number that is divisible by 5, 6 and 15 is 30

Verification

5 × 6 = 30

6 × 5 = 30

15 × 2 = 30

Answer 2

LCM of 4,5,6,15,and18

4=2×2

5=5×1

6=2×3

15=3×5

$lcm = 3 \times 5 \times 2$

$the \: lcm \: of \: the \: given \: number \: is \: 30$

$so \: the \: least \: number \: divided \: by \: 5,6,15 \: is \: 30$
