Given numbers are 654, 646, 945, 370

The list of prime factors of all numbers are

Prime factors of 654 are 2 x 3 x 109

Prime factors of 646 are 2 x 17 x 19

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 370 are 2 x 5 x 37

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

Given numbers are 654, 646, 945, 370

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

Apply this formula for all numbers.

Step1:

LCM(654, 646) = 211242

GCD(654, 646) = ( 654 x 646 ) / 211242

= 654 / 646

= 654

Step2:

LCM(2, 945) = 1890

GCD(2, 945) = ( 2 x 945 ) / 1890

= 2 / 945

= 2

Step3:

LCM(1, 370) = 370

GCD(1, 370) = ( 1 x 370 ) / 370

= 1 / 370

= 1

So, Greatest Common Divisor of 654, 646, 945, 370 is 1
