GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 502) = 99898
GCD(398, 502) = ( 398 x 502 ) / 99898
= 398 / 502
= 398
Step2:
LCM(2, 868) = 868
GCD(2, 868) = ( 2 x 868 ) / 868
= 2 / 868
= 2
Step3:
LCM(2, 736) = 736
GCD(2, 736) = ( 2 x 736 ) / 736
= 2 / 736
= 2
So, Greatest Common Divisor of 398, 502, 868, 736 is 2
