Given numbers are 138, 731, 385, 919
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(138, 731) = 100878
GCD(138, 731) = ( 138 x 731 ) / 100878
= 138 / 731
= 138
Step2:
LCM(1, 385) = 385
GCD(1, 385) = ( 1 x 385 ) / 385
= 1 / 385
= 1
Step3:
LCM(1, 919) = 919
GCD(1, 919) = ( 1 x 919 ) / 919
= 1 / 919
= 1
So, Greatest Common Divisor of 138, 731, 385, 919 is 1
