Steps to Calculate GCD of 221, 291, 347, 122 using LCM Formula
Given numbers are 221, 291, 347, 122
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 291) = 64311
GCD(221, 291) = ( 221 x 291 ) / 64311
= 221 / 291
= 221
Step2:
LCM(1, 347) = 347
GCD(1, 347) = ( 1 x 347 ) / 347
= 1 / 347
= 1
Step3:
LCM(1, 122) = 122
GCD(1, 122) = ( 1 x 122 ) / 122
= 1 / 122
= 1
So, Greatest Common Divisor of 221, 291, 347, 122 is 1
