Steps to Calculate GCD of 221, 857, 311, 395 using LCM Formula
Given numbers are 221, 857, 311, 395
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 857) = 189397
GCD(221, 857) = ( 221 x 857 ) / 189397
= 221 / 857
= 221
Step2:
LCM(1, 311) = 311
GCD(1, 311) = ( 1 x 311 ) / 311
= 1 / 311
= 1
Step3:
LCM(1, 395) = 395
GCD(1, 395) = ( 1 x 395 ) / 395
= 1 / 395
= 1
So, Greatest Common Divisor of 221, 857, 311, 395 is 1
