Question

What will be xy if 7862xy is to be divisible by 125?

Answer 1

XY= 50

786250÷125=6290

Answer 2

Concept:

Finding a number's prime factors in a way that the original number may be divided equally by them is known as prime factorization. Since a composite number might have more than two factors, this method can only be used with composite numbers rather than prime numbers.

For instance, since 2x 3x 3x 7 = 126 and 2, 3, and 7 are prime numbers, the prime factors of 126 will be 2, 3 and 7.

Given:

7862xy is to be divisible be 125

Find:

What will be xy if 7862xy is to be divisible by 125?

Solution:

7862=2 x 3931

7862 xy=2 x 3931 x.y

But 7862.xy is divisible by 125

xy must be a multiple of 125

Therefore, xy be the multiple of 125
