Question

find the LCM OF 30,60 and 80

Answer 1

Hii friend,

Prime factorisation of 30 = 2 × 3 × 5

Prime factorisation of 60 = 2²× 3 × 5

Prime factorisation of 80 = 2⁴ × 5

LCM of 30, 60 and 80 = 3 × 5 × 2⁴ = 240

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

Answer 2

Heyaa..

Let's write the given numbers as the product of prime numbers..

30 = 2 × 3 × 5

60 = 2 × 2 × 3 × 5

80 = 2 × 2 × 2 × 2 × 5

Therefore.. LCM ( 30, 60, 80 ) = 2 × 3 × 2 × 5 × 2 × 2

= 240

Hope it helps...
