Given numbers are 321, 321, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(321, 321) = 321
GCD(321, 321) = ( 321 x 321 ) / 321
= 321 / 321
= 321
Step2:
LCM(321, 257) = 82497
GCD(321, 257) = ( 321 x 257 ) / 82497
= 321 / 257
= 321
So, Greatest Common Divisor of 321, 321, 257 is 1
