Given numbers are 654, 790, 636, 485

The list of prime factors of all numbers are

Prime factors of 654 are 2 x 3 x 109

Prime factors of 790 are 2 x 5 x 79

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 485 are 5 x 97

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

Given numbers are 654, 790, 636, 485

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

Apply this formula for all numbers.

Step1:

LCM(654, 790) = 258330

GCD(654, 790) = ( 654 x 790 ) / 258330

= 654 / 790

= 654

Step2:

LCM(2, 636) = 636

GCD(2, 636) = ( 2 x 636 ) / 636

= 2 / 636

= 2

Step3:

LCM(2, 485) = 970

GCD(2, 485) = ( 2 x 485 ) / 970

= 2 / 485

= 2

So, Greatest Common Divisor of 654, 790, 636, 485 is 1
