Given numbers are 432, 177, 442, 981
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(432, 177) = 25488
GCD(432, 177) = ( 432 x 177 ) / 25488
= 432 / 177
= 432
Step2:
LCM(3, 442) = 1326
GCD(3, 442) = ( 3 x 442 ) / 1326
= 3 / 442
= 3
Step3:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
So, Greatest Common Divisor of 432, 177, 442, 981 is 1
