Given numbers are 985, 720, 102, 258

The list of prime factors of all numbers are

Prime factors of 985 are 5 x 197

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 102 are 2 x 3 x 17

Prime factors of 258 are 2 x 3 x 43

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

Given numbers are 985, 720, 102, 258

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

Apply this formula for all numbers.

Step1:

LCM(985, 720) = 141840

GCD(985, 720) = ( 985 x 720 ) / 141840

= 985 / 720

= 985

Step2:

LCM(5, 102) = 510

GCD(5, 102) = ( 5 x 102 ) / 510

= 5 / 102

= 5

Step3:

LCM(1, 258) = 258

GCD(1, 258) = ( 1 x 258 ) / 258

= 1 / 258

= 1

So, Greatest Common Divisor of 985, 720, 102, 258 is 1
