Given numbers are 985, 690, 162, 721

The list of prime factors of all numbers are

Prime factors of 985 are 5 x 197

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 162 are 2 x 3 x 3 x 3 x 3

Prime factors of 721 are 7 x 103

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

Given numbers are 985, 690, 162, 721

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

Apply this formula for all numbers.

Step1:

LCM(985, 690) = 135930

GCD(985, 690) = ( 985 x 690 ) / 135930

= 985 / 690

= 985

Step2:

LCM(5, 162) = 810

GCD(5, 162) = ( 5 x 162 ) / 810

= 5 / 162

= 5

Step3:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 985, 690, 162, 721 is 1
