GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 719) = 403359
GCD(561, 719) = ( 561 x 719 ) / 403359
= 561 / 719
= 561
Step2:
LCM(1, 966) = 966
GCD(1, 966) = ( 1 x 966 ) / 966
= 1 / 966
= 1
Step3:
LCM(1, 505) = 505
GCD(1, 505) = ( 1 x 505 ) / 505
= 1 / 505
= 1
So, Greatest Common Divisor of 561, 719, 966, 505 is 1
