Given numbers are 497, 646, 415, 393
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(497, 646) = 321062
GCD(497, 646) = ( 497 x 646 ) / 321062
= 497 / 646
= 497
Step2:
LCM(1, 415) = 415
GCD(1, 415) = ( 1 x 415 ) / 415
= 1 / 415
= 1
Step3:
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
= 1 / 393
= 1
So, Greatest Common Divisor of 497, 646, 415, 393 is 1
