Given numbers are 115, 255, 100, 147

The list of prime factors of all numbers are

Prime factors of 115 are 5 x 23

Prime factors of 255 are 3 x 5 x 17

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 147 are 3 x 7 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 115, 255, 100, 147

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(115, 255) = 5865

GCD(115, 255) = ( 115 x 255 ) / 5865

= 115 / 255

= 115

Step2:

LCM(5, 100) = 100

GCD(5, 100) = ( 5 x 100 ) / 100

= 5 / 100

= 5

Step3:

LCM(5, 147) = 735

GCD(5, 147) = ( 5 x 147 ) / 735

= 5 / 147

= 5

So, Greatest Common Divisor of 115, 255, 100, 147 is 1
