Given numbers are 857, 421, 415, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(857, 421) = 360797
GCD(857, 421) = ( 857 x 421 ) / 360797
= 857 / 421
= 857
Step2:
LCM(1, 415) = 415
GCD(1, 415) = ( 1 x 415 ) / 415
= 1 / 415
= 1
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 857, 421, 415, 649 is 1
