Question

The HCF and LCM of two numbers are 90 and 1080 respectively. If one number is 270, then the other will be

Answer 1

We know that

( HCF ×LCM)= PRODUCT OF THE NUMBER

(90 × 1080)= 270 × x

(97200) ÷ 270 = x

360 = x

So the other number is 360

Answer 2

Formula: HCF×LCM=1st no.×2nd no.
So, 90×1080÷270×x.
=360.
Hence, the other no. will be 360.
Check:
90×1080
=97200.
And,
270×360
=97200
So we have checked that both the answers are same.
