Given numbers are 613, 195, 797, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(613, 195) = 119535
GCD(613, 195) = ( 613 x 195 ) / 119535
= 613 / 195
= 613
Step2:
LCM(1, 797) = 797
GCD(1, 797) = ( 1 x 797 ) / 797
= 1 / 797
= 1
Step3:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
So, Greatest Common Divisor of 613, 195, 797, 391 is 1
