Question

14. The H.C.F. of two number is 145 and their
L.C.M. is 2175. If one of the number is 435, find
the other.
​

Answer 1

Answer:

725

Step-by-step explanation:

We have two numbers.

Let one of them be 'a' = 145

and other one be 'b' = ?

We have,

H.C.F. = 145

L.C.M. = 2175

According to Formula,

L.C.M × H.C.F = a × b

We need to find 'b'

Therefore,

b = (L.C.M. × H.C.F) ÷ a

b = (2175 × 145) ÷ 435

b = (315375) ÷ 435

thus,

b = 725

The other number 'b' is = 725
