Question

The H.C.F. of two numbers is 13 and their L.C.M. is 1989. If one of the number is
117, find out the other number​

Answer 1

Answer:

Other number= 221

Step-by-step explanation:

1st no. * 2nd no. = H.C.F. * L.C.M

HCF * LCM = 13*1989= 25857

2nd no. = 25857/117

2nd no. = 221

Answer 2

Answer:

Step-by-step explanation:

product of 2 numbers = hcf x lcm

We have given HCF = 13

LCM = 1989

One number is 117

Let the other number be x

Substitute,

product of 2 numbers= hcf x lcm

117x =13 x1989

x=13 x 1989/117

x = 221

 

Therefore, Other number is 221.
