Steps to Calculate GCD of 138, 461, 619, 355 using LCM Formula
Given numbers are 138, 461, 619, 355
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(138, 461) = 63618
GCD(138, 461) = ( 138 x 461 ) / 63618
= 138 / 461
= 138
Step2:
LCM(1, 619) = 619
GCD(1, 619) = ( 1 x 619 ) / 619
= 1 / 619
= 1
Step3:
LCM(1, 355) = 355
GCD(1, 355) = ( 1 x 355 ) / 355
= 1 / 355
= 1
So, Greatest Common Divisor of 138, 461, 619, 355 is 1
