Given numbers are 905, 645, 414, 688

The list of prime factors of all numbers are

Prime factors of 905 are 5 x 181

Prime factors of 645 are 3 x 5 x 43

Prime factors of 414 are 2 x 3 x 3 x 23

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

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

Given numbers are 905, 645, 414, 688

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

Apply this formula for all numbers.

Step1:

LCM(905, 645) = 116745

GCD(905, 645) = ( 905 x 645 ) / 116745

= 905 / 645

= 905

Step2:

LCM(5, 414) = 2070

GCD(5, 414) = ( 5 x 414 ) / 2070

= 5 / 414

= 5

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 905, 645, 414, 688 is 1
