Given numbers are 385, 725, 634, 180
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 725) = 55825
GCD(385, 725) = ( 385 x 725 ) / 55825
= 385 / 725
= 385
Step2:
LCM(5, 634) = 3170
GCD(5, 634) = ( 5 x 634 ) / 3170
= 5 / 634
= 5
Step3:
LCM(1, 180) = 180
GCD(1, 180) = ( 1 x 180 ) / 180
= 1 / 180
= 1
So, Greatest Common Divisor of 385, 725, 634, 180 is 1
