GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 130) = 10010
GCD(385, 130) = ( 385 x 130 ) / 10010
= 385 / 130
= 385
Step2:
LCM(5, 172) = 860
GCD(5, 172) = ( 5 x 172 ) / 860
= 5 / 172
= 5
So, Greatest Common Divisor of 385, 130, 172 is 1
