GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(921, 517) = 476157
GCD(921, 517) = ( 921 x 517 ) / 476157
= 921 / 517
= 921
Step2:
LCM(1, 845) = 845
GCD(1, 845) = ( 1 x 845 ) / 845
= 1 / 845
= 1
Step3:
LCM(1, 419) = 419
GCD(1, 419) = ( 1 x 419 ) / 419
= 1 / 419
= 1
So, Greatest Common Divisor of 921, 517, 845, 419 is 1
