Given numbers are 978, 645, 510, 635

The list of prime factors of all numbers are

Prime factors of 978 are 2 x 3 x 163

Prime factors of 645 are 3 x 5 x 43

Prime factors of 510 are 2 x 3 x 5 x 17

Prime factors of 635 are 5 x 127

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

Given numbers are 978, 645, 510, 635

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

Apply this formula for all numbers.

Step1:

LCM(978, 645) = 210270

GCD(978, 645) = ( 978 x 645 ) / 210270

= 978 / 645

= 978

Step2:

LCM(3, 510) = 510

GCD(3, 510) = ( 3 x 510 ) / 510

= 3 / 510

= 3

Step3:

LCM(3, 635) = 1905

GCD(3, 635) = ( 3 x 635 ) / 1905

= 3 / 635

= 3

So, Greatest Common Divisor of 978, 645, 510, 635 is 1
