Given numbers are 432, 939, 390, 115
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(432, 939) = 135216
GCD(432, 939) = ( 432 x 939 ) / 135216
= 432 / 939
= 432
Step2:
LCM(3, 390) = 390
GCD(3, 390) = ( 3 x 390 ) / 390
= 3 / 390
= 3
Step3:
LCM(3, 115) = 345
GCD(3, 115) = ( 3 x 115 ) / 345
= 3 / 115
= 3
So, Greatest Common Divisor of 432, 939, 390, 115 is 1
