GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(494, 686) = 169442
GCD(494, 686) = ( 494 x 686 ) / 169442
= 494 / 686
= 494
Step2:
LCM(2, 144) = 144
GCD(2, 144) = ( 2 x 144 ) / 144
= 2 / 144
= 2
Step3:
LCM(2, 845) = 1690
GCD(2, 845) = ( 2 x 845 ) / 1690
= 2 / 845
= 2
So, Greatest Common Divisor of 494, 686, 144, 845 is 1
