Given numbers are 857, 171, 780, 889
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(857, 171) = 146547
GCD(857, 171) = ( 857 x 171 ) / 146547
= 857 / 171
= 857
Step2:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
Step3:
LCM(1, 889) = 889
GCD(1, 889) = ( 1 x 889 ) / 889
= 1 / 889
= 1
So, Greatest Common Divisor of 857, 171, 780, 889 is 1
