GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(769, 447) = 343743
GCD(769, 447) = ( 769 x 447 ) / 343743
= 769 / 447
= 769
Step2:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
Step3:
LCM(1, 681) = 681
GCD(1, 681) = ( 1 x 681 ) / 681
= 1 / 681
= 1
So, Greatest Common Divisor of 769, 447, 639, 681 is 1
