Given numbers are 138, 891, 579, 407
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(138, 891) = 40986
GCD(138, 891) = ( 138 x 891 ) / 40986
= 138 / 891
= 138
Step2:
LCM(3, 579) = 579
GCD(3, 579) = ( 3 x 579 ) / 579
= 3 / 579
= 3
Step3:
LCM(3, 407) = 1221
GCD(3, 407) = ( 3 x 407 ) / 1221
= 3 / 407
= 3
So, Greatest Common Divisor of 138, 891, 579, 407 is 1
