Given numbers are 198, 385, 432, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(198, 385) = 6930
GCD(198, 385) = ( 198 x 385 ) / 6930
= 198 / 385
= 198
Step2:
LCM(11, 432) = 4752
GCD(11, 432) = ( 11 x 432 ) / 4752
= 11 / 432
= 11
Step3:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
So, Greatest Common Divisor of 198, 385, 432, 865 is 1
