Given numbers are 654, 161, 583, 640

The list of prime factors of all numbers are

Prime factors of 654 are 2 x 3 x 109

Prime factors of 161 are 7 x 23

Prime factors of 583 are 11 x 53

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 654, 161, 583, 640

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

Apply this formula for all numbers.

Step1:

LCM(654, 161) = 105294

GCD(654, 161) = ( 654 x 161 ) / 105294

= 654 / 161

= 654

Step2:

LCM(1, 583) = 583

GCD(1, 583) = ( 1 x 583 ) / 583

= 1 / 583

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 654, 161, 583, 640 is 1
