Given numbers are 645, 585, 661, 926

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 585 are 3 x 3 x 5 x 13

Prime factors of 661 are 661

Prime factors of 926 are 2 x 463

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

Given numbers are 645, 585, 661, 926

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

Apply this formula for all numbers.

Step1:

LCM(645, 585) = 25155

GCD(645, 585) = ( 645 x 585 ) / 25155

= 645 / 585

= 645

Step2:

LCM(15, 661) = 9915

GCD(15, 661) = ( 15 x 661 ) / 9915

= 15 / 661

= 15

Step3:

LCM(1, 926) = 926

GCD(1, 926) = ( 1 x 926 ) / 926

= 1 / 926

= 1

So, Greatest Common Divisor of 645, 585, 661, 926 is 1
