Given numbers are 868, 988, 31, 623

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

Apply this formula for all numbers.

Step1:

LCM(868, 988) = 214396

GCD(868, 988) = ( 868 x 988 ) / 214396

= 868 / 988

= 868

Step2:

LCM(4, 31) = 124

GCD(4, 31) = ( 4 x 31 ) / 124

= 4 / 31

= 4

Step3:

LCM(1, 623) = 623

GCD(1, 623) = ( 1 x 623 ) / 623

= 1 / 623

= 1

So, Greatest Common Divisor of 868, 988, 31, 623 is 1
