Given numbers are 686, 842, 853, 909
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 842) = 288806
GCD(686, 842) = ( 686 x 842 ) / 288806
= 686 / 842
= 686
Step2:
LCM(2, 853) = 1706
GCD(2, 853) = ( 2 x 853 ) / 1706
= 2 / 853
= 2
Step3:
LCM(1, 909) = 909
GCD(1, 909) = ( 1 x 909 ) / 909
= 1 / 909
= 1
So, Greatest Common Divisor of 686, 842, 853, 909 is 1
