Question

If Lcm of two no. Is 2079 and their HCF is 27 if one of the numbers is 297 find the other no.

Answer 1

let the other no. is Y
then
LCM × HCF = 297× Y
2079×27 = 297 × Y
Y = (2079×27) / 297
Y = 189
hence the other no. is 189

Answer 2

LCM X HCF= product of two numbers

2079 x 27= 297 x other number

56133  divided by 297= other number

189 = to the other number.

verification -

2079 x27= 297 x 189

56133 = 56133
