Given numbers are 921, 561, 232, 432
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(921, 561) = 172227
GCD(921, 561) = ( 921 x 561 ) / 172227
= 921 / 561
= 921
Step2:
LCM(3, 232) = 696
GCD(3, 232) = ( 3 x 232 ) / 696
= 3 / 232
= 3
Step3:
LCM(1, 432) = 432
GCD(1, 432) = ( 1 x 432 ) / 432
= 1 / 432
= 1
So, Greatest Common Divisor of 921, 561, 232, 432 is 1
