GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(839, 649) = 544511
GCD(839, 649) = ( 839 x 649 ) / 544511
= 839 / 649
= 839
Step2:
LCM(1, 568) = 568
GCD(1, 568) = ( 1 x 568 ) / 568
= 1 / 568
= 1
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 839, 649, 568, 646 is 1
