Given numbers are 138, 379, 817, 423
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(138, 379) = 52302
GCD(138, 379) = ( 138 x 379 ) / 52302
= 138 / 379
= 138
Step2:
LCM(1, 817) = 817
GCD(1, 817) = ( 1 x 817 ) / 817
= 1 / 817
= 1
Step3:
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
= 1 / 423
= 1
So, Greatest Common Divisor of 138, 379, 817, 423 is 1
