Given numbers are 561, 293, 111, 771
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 293) = 164373
GCD(561, 293) = ( 561 x 293 ) / 164373
= 561 / 293
= 561
Step2:
LCM(1, 111) = 111
GCD(1, 111) = ( 1 x 111 ) / 111
= 1 / 111
= 1
Step3:
LCM(1, 771) = 771
GCD(1, 771) = ( 1 x 771 ) / 771
= 1 / 771
= 1
So, Greatest Common Divisor of 561, 293, 111, 771 is 1
