Question

find the smallest perfect square divisible by 3,4,5 and 6

Answer 1

Answer:

The required perfect square is 900

Step-by-step explanation:

In LCM 3 And 5 are not in pairs.

So, we sould multiple it by 3 And 5

i.e. 6 × 15 = 90

Hence, the required perfect square is 900.

Answer 2

Step-by-step explanation:

LCM of 3,4,5,6 are 60.

PRIME FACTORIZATION OF 60

2,2,3,5

2 IS IN PAIR BUT 3 AND 5 IS NOT IN PAIR

SO, FIRST MULTIPLY THEM BOTH THEN MULTIPLY 60 WITH THE ANS.

3*5*60

15*60

900.

THEREFORE 900 IS YOUR ANS.
