GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(404, 644) = 65044
GCD(404, 644) = ( 404 x 644 ) / 65044
= 404 / 644
= 404
Step2:
LCM(4, 728) = 728
GCD(4, 728) = ( 4 x 728 ) / 728
= 4 / 728
= 4
Step3:
LCM(4, 779) = 3116
GCD(4, 779) = ( 4 x 779 ) / 3116
= 4 / 779
= 4
So, Greatest Common Divisor of 404, 644, 728, 779 is 1
