Given numbers are 645, 858, 682, 763

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 682 are 2 x 11 x 31

Prime factors of 763 are 7 x 109

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

Given numbers are 645, 858, 682, 763

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

Apply this formula for all numbers.

Step1:

LCM(645, 858) = 184470

GCD(645, 858) = ( 645 x 858 ) / 184470

= 645 / 858

= 645

Step2:

LCM(3, 682) = 2046

GCD(3, 682) = ( 3 x 682 ) / 2046

= 3 / 682

= 3

Step3:

LCM(1, 763) = 763

GCD(1, 763) = ( 1 x 763 ) / 763

= 1 / 763

= 1

So, Greatest Common Divisor of 645, 858, 682, 763 is 1
