Given numbers are 857, 721, 372, 556
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(857, 721) = 617897
GCD(857, 721) = ( 857 x 721 ) / 617897
= 857 / 721
= 857
Step2:
LCM(1, 372) = 372
GCD(1, 372) = ( 1 x 372 ) / 372
= 1 / 372
= 1
Step3:
LCM(1, 556) = 556
GCD(1, 556) = ( 1 x 556 ) / 556
= 1 / 556
= 1
So, Greatest Common Divisor of 857, 721, 372, 556 is 1
