Given numbers are 320, 750, 909, 686
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(320, 750) = 24000
GCD(320, 750) = ( 320 x 750 ) / 24000
= 320 / 750
= 320
Step2:
LCM(10, 909) = 9090
GCD(10, 909) = ( 10 x 909 ) / 9090
= 10 / 909
= 10
Step3:
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
So, Greatest Common Divisor of 320, 750, 909, 686 is 1
