Given numbers are 654, 645, 788, 740

The list of prime factors of all numbers are

Prime factors of 654 are 2 x 3 x 109

Prime factors of 645 are 3 x 5 x 43

Prime factors of 788 are 2 x 2 x 197

Prime factors of 740 are 2 x 2 x 5 x 37

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

Given numbers are 654, 645, 788, 740

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

Apply this formula for all numbers.

Step1:

LCM(654, 645) = 140610

GCD(654, 645) = ( 654 x 645 ) / 140610

= 654 / 645

= 654

Step2:

LCM(3, 788) = 2364

GCD(3, 788) = ( 3 x 788 ) / 2364

= 3 / 788

= 3

Step3:

LCM(1, 740) = 740

GCD(1, 740) = ( 1 x 740 ) / 740

= 1 / 740

= 1

So, Greatest Common Divisor of 654, 645, 788, 740 is 1
