Question

The ratio of two numbers is 5:7 and their H.C.F is 13 , Let us find the number​

Answer 1

Answer:

Product of two numbers is equal to the product of their LCM and HCF.

So, we have:

(15x) (11x) = (2145) (13)

x2 = 132

so, x = 13

Thus, the two numbers are 195 and 143.

Answer 2

Answer:

If the ratio of two numbers is 5:7 and their H.C.F is 13, then the numbers are 65 and 91.​

Step-by-step explanation:

The highest common factor (H.C.F) of two or more numbers is the greatest number that divides each of them exactly.

From given,

let the numbers be,

5x,7x

since given,

HCF=13

we have,

5 × 13= 65

7 × 13=91

65,91 are the numbers
