Given numbers are 770, 738, 375, 645

The list of prime factors of all numbers are

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 738 are 2 x 3 x 3 x 41

Prime factors of 375 are 3 x 5 x 5 x 5

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 770, 738, 375, 645

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

Apply this formula for all numbers.

Step1:

LCM(770, 738) = 284130

GCD(770, 738) = ( 770 x 738 ) / 284130

= 770 / 738

= 770

Step2:

LCM(2, 375) = 750

GCD(2, 375) = ( 2 x 375 ) / 750

= 2 / 375

= 2

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 770, 738, 375, 645 is 1
