GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(812, 808) = 164024
GCD(812, 808) = ( 812 x 808 ) / 164024
= 812 / 808
= 812
Step2:
LCM(4, 124) = 124
GCD(4, 124) = ( 4 x 124 ) / 124
= 4 / 124
= 4
Step3:
LCM(4, 428) = 428
GCD(4, 428) = ( 4 x 428 ) / 428
= 4 / 428
= 4
So, Greatest Common Divisor of 812, 808, 124, 428 is 4
