Question

The HCF and LCM of two numbers are 45 and 175 respectively.if one of the numbers is 9 find the other.

Answer 1

Answer:

let the numbers be a and b

a = 9

use the property

hcf x LCM = product of two numbers

45 x 174 = 9 x b

so, b = 174 x 5 = 870

Answer 2

Answer:

Second number = 875

Step-by-step explanation:

tere Is a formula in 1st chapter that

HCF × LCM = PRODUCT OF THAT 2 NUMBERS

one no. is given = 9

second is = x

HCF×LCM=9×x

45×175=9×x

x= 45×175/9

x=875
