Given numbers are 645, 135, 616, 826

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 135 are 3 x 3 x 3 x 5

Prime factors of 616 are 2 x 2 x 2 x 7 x 11

Prime factors of 826 are 2 x 7 x 59

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

Given numbers are 645, 135, 616, 826

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

Apply this formula for all numbers.

Step1:

LCM(645, 135) = 5805

GCD(645, 135) = ( 645 x 135 ) / 5805

= 645 / 135

= 645

Step2:

LCM(15, 616) = 9240

GCD(15, 616) = ( 15 x 616 ) / 9240

= 15 / 616

= 15

Step3:

LCM(1, 826) = 826

GCD(1, 826) = ( 1 x 826 ) / 826

= 1 / 826

= 1

So, Greatest Common Divisor of 645, 135, 616, 826 is 1
