Question

H. c. f. of 2 no. is 145 and then lcm is2175 if one no. is 725 find the other

Answer 1

a = 725

b =?

HCF = 145

LCM = 2175

Now,

LCM × HCF = a × b

=> 145 × 2175 = 725 × b

=> 2175 × 145 / 725 = b

=> b = 2175 / 5

=> b = 435

Second number = 435

Answer 2

we know that hcf ×lcm=product of numbers
145×2175=725×x
So, x= (145×2175)/725
=435
other number is 6.
