Given numbers are 321, 257, 649, 565
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(321, 257) = 82497
GCD(321, 257) = ( 321 x 257 ) / 82497
= 321 / 257
= 321
Step2:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
Step3:
LCM(1, 565) = 565
GCD(1, 565) = ( 1 x 565 ) / 565
= 1 / 565
= 1
So, Greatest Common Divisor of 321, 257, 649, 565 is 1
