Question

hcf and LCm of two no. are 13 and 1989 if one no. is 117 find the other no.​

Answer 1

Answer:

we know that hcf×lcm=first number×second number.

So, therefore the other number=1989×13/117=221.

Answer 2

Answer:

the other number is 221

Step-by-step explanation:

let the other number be X

HCF ( 117, X ) = 13

LCM ( 117, X) = 1989

HCF(117, X ) × LCM (117, X) = 117 × X

13 × 1989 = 117 × X

25857 = 117 × X

25857 / 117 = X

221 = X
