Given numbers are 981, 868, 825, 168

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 868 are 2 x 2 x 7 x 31

Prime factors of 825 are 3 x 5 x 5 x 11

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

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

Given numbers are 981, 868, 825, 168

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

Apply this formula for all numbers.

Step1:

LCM(981, 868) = 851508

GCD(981, 868) = ( 981 x 868 ) / 851508

= 981 / 868

= 981

Step2:

LCM(1, 825) = 825

GCD(1, 825) = ( 1 x 825 ) / 825

= 1 / 825

= 1

Step3:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

So, Greatest Common Divisor of 981, 868, 825, 168 is 1
