Given numbers are 741, 939, 646, 769
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(741, 939) = 231933
GCD(741, 939) = ( 741 x 939 ) / 231933
= 741 / 939
= 741
Step2:
LCM(3, 646) = 1938
GCD(3, 646) = ( 3 x 646 ) / 1938
= 3 / 646
= 3
Step3:
LCM(1, 769) = 769
GCD(1, 769) = ( 1 x 769 ) / 769
= 1 / 769
= 1
So, Greatest Common Divisor of 741, 939, 646, 769 is 1
