The least number which is exactly divisible by 125, 75, 150 and 70?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 5250.
Prime factorization
⇒ 125 = 53
⇒ 75 = 3 × 52
⇒ 150 = 2 × 3 × 52
⇒ 70 = 2 × 5 × 7
L.C.M(125, 75, 150, and 70) = 2 × 3 × 53 × 7 = 5250
Hence,
The least number which is exactly divisible by 125, 75, 150, and 70 is 5250
