Steps to Calculate GCD of 388, 290, 27, 133 using LCM Formula
Given numbers are 388, 290, 27, 133
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(388, 290) = 56260
GCD(388, 290) = ( 388 x 290 ) / 56260
= 388 / 290
= 388
Step2:
LCM(2, 27) = 54
GCD(2, 27) = ( 2 x 27 ) / 54
= 2 / 27
= 2
Step3:
LCM(1, 133) = 133
GCD(1, 133) = ( 1 x 133 ) / 133
= 1 / 133
= 1
So, Greatest Common Divisor of 388, 290, 27, 133 is 1
