Given numbers are 857, 457, 170, 728
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(857, 457) = 391649
GCD(857, 457) = ( 857 x 457 ) / 391649
= 857 / 457
= 857
Step2:
LCM(1, 170) = 170
GCD(1, 170) = ( 1 x 170 ) / 170
= 1 / 170
= 1
Step3:
LCM(1, 728) = 728
GCD(1, 728) = ( 1 x 728 ) / 728
= 1 / 728
= 1
So, Greatest Common Divisor of 857, 457, 170, 728 is 1
