Given numbers are 390, 468, 791, 321
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 468) = 2340
GCD(390, 468) = ( 390 x 468 ) / 2340
= 390 / 468
= 390
Step2:
LCM(78, 791) = 61698
GCD(78, 791) = ( 78 x 791 ) / 61698
= 78 / 791
= 78
Step3:
LCM(1, 321) = 321
GCD(1, 321) = ( 1 x 321 ) / 321
= 1 / 321
= 1
So, Greatest Common Divisor of 390, 468, 791, 321 is 1
