Given numbers are 138, 579, 671, 471
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(138, 579) = 26634
GCD(138, 579) = ( 138 x 579 ) / 26634
= 138 / 579
= 138
Step2:
LCM(3, 671) = 2013
GCD(3, 671) = ( 3 x 671 ) / 2013
= 3 / 671
= 3
Step3:
LCM(1, 471) = 471
GCD(1, 471) = ( 1 x 471 ) / 471
= 1 / 471
= 1
So, Greatest Common Divisor of 138, 579, 671, 471 is 1
