Given numbers are 321, 813, 438, 791
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(321, 813) = 86991
GCD(321, 813) = ( 321 x 813 ) / 86991
= 321 / 813
= 321
Step2:
LCM(3, 438) = 438
GCD(3, 438) = ( 3 x 438 ) / 438
= 3 / 438
= 3
Step3:
LCM(3, 791) = 2373
GCD(3, 791) = ( 3 x 791 ) / 2373
= 3 / 791
= 3
So, Greatest Common Divisor of 321, 813, 438, 791 is 1
