Given numbers are 385, 726, 139, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 726) = 25410
GCD(385, 726) = ( 385 x 726 ) / 25410
= 385 / 726
= 385
Step2:
LCM(11, 139) = 1529
GCD(11, 139) = ( 11 x 139 ) / 1529
= 11 / 139
= 11
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 385, 726, 139, 644 is 1
