Given numbers are 988, 931, 688, 530

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

Apply this formula for all numbers.

Step1:

LCM(988, 931) = 48412

GCD(988, 931) = ( 988 x 931 ) / 48412

= 988 / 931

= 988

Step2:

LCM(19, 688) = 13072

GCD(19, 688) = ( 19 x 688 ) / 13072

= 19 / 688

= 19

Step3:

LCM(1, 530) = 530

GCD(1, 530) = ( 1 x 530 ) / 530

= 1 / 530

= 1

So, Greatest Common Divisor of 988, 931, 688, 530 is 1
