Given numbers are 985, 624, 146, 690

The list of prime factors of all numbers are

Prime factors of 985 are 5 x 197

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

Prime factors of 146 are 2 x 73

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

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

Given numbers are 985, 624, 146, 690

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

Apply this formula for all numbers.

Step1:

LCM(985, 624) = 614640

GCD(985, 624) = ( 985 x 624 ) / 614640

= 985 / 624

= 985

Step2:

LCM(1, 146) = 146

GCD(1, 146) = ( 1 x 146 ) / 146

= 1 / 146

= 1

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 985, 624, 146, 690 is 1
