Given numbers are 138, 356, 855, 344
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(138, 356) = 24564
GCD(138, 356) = ( 138 x 356 ) / 24564
= 138 / 356
= 138
Step2:
LCM(2, 855) = 1710
GCD(2, 855) = ( 2 x 855 ) / 1710
= 2 / 855
= 2
Step3:
LCM(1, 344) = 344
GCD(1, 344) = ( 1 x 344 ) / 344
= 1 / 344
= 1
So, Greatest Common Divisor of 138, 356, 855, 344 is 1
