Given numbers are 978, 728, 715, 306

The list of prime factors of all numbers are

Prime factors of 978 are 2 x 3 x 163

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 715 are 5 x 11 x 13

Prime factors of 306 are 2 x 3 x 3 x 17

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

Given numbers are 978, 728, 715, 306

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

Apply this formula for all numbers.

Step1:

LCM(978, 728) = 355992

GCD(978, 728) = ( 978 x 728 ) / 355992

= 978 / 728

= 978

Step2:

LCM(2, 715) = 1430

GCD(2, 715) = ( 2 x 715 ) / 1430

= 2 / 715

= 2

Step3:

LCM(1, 306) = 306

GCD(1, 306) = ( 1 x 306 ) / 306

= 1 / 306

= 1

So, Greatest Common Divisor of 978, 728, 715, 306 is 1
