GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 665) = 326515
GCD(491, 665) = ( 491 x 665 ) / 326515
= 491 / 665
= 491
Step2:
LCM(1, 845) = 845
GCD(1, 845) = ( 1 x 845 ) / 845
= 1 / 845
= 1
Step3:
LCM(1, 997) = 997
GCD(1, 997) = ( 1 x 997 ) / 997
= 1 / 997
= 1
So, Greatest Common Divisor of 491, 665, 845, 997 is 1
