Given numbers are 654, 506, 665, 308

The list of prime factors of all numbers are

Prime factors of 654 are 2 x 3 x 109

Prime factors of 506 are 2 x 11 x 23

Prime factors of 665 are 5 x 7 x 19

Prime factors of 308 are 2 x 2 x 7 x 11

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

Given numbers are 654, 506, 665, 308

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

Apply this formula for all numbers.

Step1:

LCM(654, 506) = 165462

GCD(654, 506) = ( 654 x 506 ) / 165462

= 654 / 506

= 654

Step2:

LCM(2, 665) = 1330

GCD(2, 665) = ( 2 x 665 ) / 1330

= 2 / 665

= 2

Step3:

LCM(1, 308) = 308

GCD(1, 308) = ( 1 x 308 ) / 308

= 1 / 308

= 1

So, Greatest Common Divisor of 654, 506, 665, 308 is 1
