Question

Lcm of two nos is 1920 and hcf 16.If no. Is 128 what will be the otger
kese ​

Answer 1

It's a known fact that

LCM * HCF = a*b

So

$1920 \times 16 = 128 \times a \\ 30720 = 128 \times a \\ a = 30720 \div 128 \\ a = 240$

Answer 2

LCM*HCF=product of two numbers

let second number be x

then ATQ

1920*16=128*x

x== 1920*16 divide 128

x=30720divide128

x=240.

other number =240
