GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(622, 994) = 309134
GCD(622, 994) = ( 622 x 994 ) / 309134
= 622 / 994
= 622
Step2:
LCM(2, 381) = 762
GCD(2, 381) = ( 2 x 381 ) / 762
= 2 / 381
= 2
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 622, 994, 381, 561 is 1
