Question

the smallest square number which is divisible by 14 28 and 35

Answer 1

Answer:

L.C.M. of 8, 15 and 20 is 120.

Prime factors of 120 = 2 x 2 x 2 x 3 x 5

Here, prime factors 2, 3 and 5 have no pair.

Therefore 120 must be multiplied by 2 x 3 x 5 to make it a perfect square.

\therefore120\times2\times3\times5=3600∴120×2×3×5=3600

Hence, the smallest square number which is divisible by 8, 15 and 20 is 3600.

Answer 2

Answer:

Step-by-step explanation:

Since we have to find the dividend we will find the LCM of given numbers

14=7*2

28=4*7

35=7*5

55=5*11

The LCM is 7*4*5*11=1540

Since this number leaves remainder of 5 we will add 5 to this number so the answer is 1540+5

1545
