Given numbers are 559, 663, 209, 721
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(559, 663) = 28509
GCD(559, 663) = ( 559 x 663 ) / 28509
= 559 / 663
= 559
Step2:
LCM(13, 209) = 2717
GCD(13, 209) = ( 13 x 209 ) / 2717
= 13 / 209
= 13
Step3:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
So, Greatest Common Divisor of 559, 663, 209, 721 is 1
