Given numbers are 561, 293, 686, 566
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, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
Step3:
LCM(1, 566) = 566
GCD(1, 566) = ( 1 x 566 ) / 566
= 1 / 566
= 1
So, Greatest Common Divisor of 561, 293, 686, 566 is 1
