Given numbers are 647, 619, 235, 720

The list of prime factors of all numbers are

Prime factors of 647 are 647

Prime factors of 619 are 619

Prime factors of 235 are 5 x 47

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 647, 619, 235, 720

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

Apply this formula for all numbers.

Step1:

LCM(647, 619) = 400493

GCD(647, 619) = ( 647 x 619 ) / 400493

= 647 / 619

= 647

Step2:

LCM(1, 235) = 235

GCD(1, 235) = ( 1 x 235 ) / 235

= 1 / 235

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 647, 619, 235, 720 is 1
