Question

Find the lcm of two number , if there product is 140 and the hcf is 2

Answer 1

Sol : Given, 

Product of numbers = 140

H.C.F of those numbers = 2.

We know that,

 L.C.M x H.C.F = Product of numbers

 L.C.M x 2 = 140

 L.C.M = 140 / 2

 L.C.M = 70

Answer 2

Answer:

L.C.M of two number is 70

Step-by-step explanation:

Given,  

Let the two number be  a, and b

Product of numbers =  a * b = 140

H.C.F of two numbers ( a, b)= 2.

As We know the formula,

 L.C.M x H.C.F =  a * b = Product of numbers

 Now put the given value on the formula

L.C.M x 2 = 140

L.C.M = 140 / 2

Hence,  L.C.M of two number is 70 .
