Steps to Calculate GCD of 388, 321, 23, 357 using LCM Formula
Given numbers are 388, 321, 23, 357
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(388, 321) = 124548
GCD(388, 321) = ( 388 x 321 ) / 124548
= 388 / 321
= 388
Step2:
LCM(1, 23) = 23
GCD(1, 23) = ( 1 x 23 ) / 23
= 1 / 23
= 1
Step3:
LCM(1, 357) = 357
GCD(1, 357) = ( 1 x 357 ) / 357
= 1 / 357
= 1
So, Greatest Common Divisor of 388, 321, 23, 357 is 1
