GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(947, 686) = 649642
GCD(947, 686) = ( 947 x 686 ) / 649642
= 947 / 686
= 947
Step2:
LCM(1, 569) = 569
GCD(1, 569) = ( 1 x 569 ) / 569
= 1 / 569
= 1
Step3:
LCM(1, 945) = 945
GCD(1, 945) = ( 1 x 945 ) / 945
= 1 / 945
= 1
So, Greatest Common Divisor of 947, 686, 569, 945 is 1
