Given numbers are 500, 155, 647, 426

The list of prime factors of all numbers are

Prime factors of 500 are 2 x 2 x 5 x 5 x 5

Prime factors of 155 are 5 x 31

Prime factors of 647 are 647

Prime factors of 426 are 2 x 3 x 71

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

Given numbers are 500, 155, 647, 426

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

Apply this formula for all numbers.

Step1:

LCM(500, 155) = 15500

GCD(500, 155) = ( 500 x 155 ) / 15500

= 500 / 155

= 500

Step2:

LCM(5, 647) = 3235

GCD(5, 647) = ( 5 x 647 ) / 3235

= 5 / 647

= 5

Step3:

LCM(1, 426) = 426

GCD(1, 426) = ( 1 x 426 ) / 426

= 1 / 426

= 1

So, Greatest Common Divisor of 500, 155, 647, 426 is 1
