Steps to Calculate GCD of 857, 413, 128, 231 using LCM Formula
Given numbers are 857, 413, 128, 231
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(857, 413) = 353941
GCD(857, 413) = ( 857 x 413 ) / 353941
= 857 / 413
= 857
Step2:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
Step3:
LCM(1, 231) = 231
GCD(1, 231) = ( 1 x 231 ) / 231
= 1 / 231
= 1
So, Greatest Common Divisor of 857, 413, 128, 231 is 1
