Question

Two numbers are in the ratio 4:7.If their L.C.M. IS 168 find the numbers

Answer 1

Step-by-step explanation:

let the number be 4a and 7a

LCM =168

HCF =a

we know that , product of number =LCM×HCF

4a×7a=168a

28a^2 =168a

28a =168

a =6

First number =4×6=24

second number =7×6=42

I hope that it will help you

Answer 2

Answer:

24 and42

Step-by-step explanation:

let the numbers be x

so numbers = 4x and 7x

LCM of two number × HCF of two number= product of two number

Taking 4x and 7x , x is the HCF

LCM ×x=4x×7x

168=28x

x=6

numbers are 7x=7×6= 42

4x =4×6=24
