Given numbers are 978, 975, 784, 679

The list of prime factors of all numbers are

Prime factors of 978 are 2 x 3 x 163

Prime factors of 975 are 3 x 5 x 5 x 13

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 679 are 7 x 97

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

Given numbers are 978, 975, 784, 679

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

Apply this formula for all numbers.

Step1:

LCM(978, 975) = 317850

GCD(978, 975) = ( 978 x 975 ) / 317850

= 978 / 975

= 978

Step2:

LCM(3, 784) = 2352

GCD(3, 784) = ( 3 x 784 ) / 2352

= 3 / 784

= 3

Step3:

LCM(1, 679) = 679

GCD(1, 679) = ( 1 x 679 ) / 679

= 1 / 679

= 1

So, Greatest Common Divisor of 978, 975, 784, 679 is 1
