Given numbers are 812, 676, 623, 989

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

Apply this formula for all numbers.

Step1:

LCM(812, 676) = 137228

GCD(812, 676) = ( 812 x 676 ) / 137228

= 812 / 676

= 812

Step2:

LCM(4, 623) = 2492

GCD(4, 623) = ( 4 x 623 ) / 2492

= 4 / 623

= 4

Step3:

LCM(1, 989) = 989

GCD(1, 989) = ( 1 x 989 ) / 989

= 1 / 989

= 1

So, Greatest Common Divisor of 812, 676, 623, 989 is 1
