Given numbers are 385, 865, 432, 427
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 865) = 66605
GCD(385, 865) = ( 385 x 865 ) / 66605
= 385 / 865
= 385
Step2:
LCM(5, 432) = 2160
GCD(5, 432) = ( 5 x 432 ) / 2160
= 5 / 432
= 5
Step3:
LCM(1, 427) = 427
GCD(1, 427) = ( 1 x 427 ) / 427
= 1 / 427
= 1
So, Greatest Common Divisor of 385, 865, 432, 427 is 1
