Given numbers are 990, 985, 465, 688

The list of prime factors of all numbers are

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 985 are 5 x 197

Prime factors of 465 are 3 x 5 x 31

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

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

Given numbers are 990, 985, 465, 688

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

Apply this formula for all numbers.

Step1:

LCM(990, 985) = 195030

GCD(990, 985) = ( 990 x 985 ) / 195030

= 990 / 985

= 990

Step2:

LCM(5, 465) = 465

GCD(5, 465) = ( 5 x 465 ) / 465

= 5 / 465

= 5

Step3:

LCM(5, 688) = 3440

GCD(5, 688) = ( 5 x 688 ) / 3440

= 5 / 688

= 5

So, Greatest Common Divisor of 990, 985, 465, 688 is 1
