Given numbers are 115, 420, 589, 667
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(115, 420) = 9660
GCD(115, 420) = ( 115 x 420 ) / 9660
= 115 / 420
= 115
Step2:
LCM(5, 589) = 2945
GCD(5, 589) = ( 5 x 589 ) / 2945
= 5 / 589
= 5
Step3:
LCM(1, 667) = 667
GCD(1, 667) = ( 1 x 667 ) / 667
= 1 / 667
= 1
So, Greatest Common Divisor of 115, 420, 589, 667 is 1
