Given numbers are 139, 140, 124
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(139, 140) = 19460
GCD(139, 140) = ( 139 x 140 ) / 19460
= 139 / 140
= 139
Step2:
LCM(1, 124) = 124
GCD(1, 124) = ( 1 x 124 ) / 124
= 1 / 124
= 1
So, Greatest Common Divisor of 139, 140, 124 is 1
