Given numbers are 138, 650, 758, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(138, 650) = 44850
GCD(138, 650) = ( 138 x 650 ) / 44850
= 138 / 650
= 138
Step2:
LCM(2, 758) = 758
GCD(2, 758) = ( 2 x 758 ) / 758
= 2 / 758
= 2
Step3:
LCM(2, 391) = 782
GCD(2, 391) = ( 2 x 391 ) / 782
= 2 / 391
= 2
So, Greatest Common Divisor of 138, 650, 758, 391 is 1
