Question

find the LCM and HCF of 40 36 126

Answer 1

Heya !!!




Prime factorisation of 40 = 2 × 2 × 2 × 5



Prime factorisation of 36 = 2 × 2 × 3 × 3


Prime factorisation of 126 = 2 × 3 × 3 × 7



HCF of 40 , 36 , 126 = 2


And,


LCM of 40 , 36 , 126 = 2520.





HOPE IT WILL HELP YOU...... :-)

Answer 2

Hi,

Here is your answer,

We need to use Prime Factorisation Method

 → 40 = 2×2×2×5 →  36 = 2×2×3×3       
→ 126 = 2×3×3×7

H.C.F(40,36,126) → 2 
L.C.M(40,36,126) → 2520.

Hope it helps you !
