Given numbers are 738, 500, 978, 645

The list of prime factors of all numbers are

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

Prime factors of 500 are 2 x 2 x 5 x 5 x 5

Prime factors of 978 are 2 x 3 x 163

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 738, 500, 978, 645

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

Apply this formula for all numbers.

Step1:

LCM(738, 500) = 184500

GCD(738, 500) = ( 738 x 500 ) / 184500

= 738 / 500

= 738

Step2:

LCM(2, 978) = 978

GCD(2, 978) = ( 2 x 978 ) / 978

= 2 / 978

= 2

Step3:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

So, Greatest Common Divisor of 738, 500, 978, 645 is 1
