Given numbers are 398, 459, 464, 515
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 459) = 182682
GCD(398, 459) = ( 398 x 459 ) / 182682
= 398 / 459
= 398
Step2:
LCM(1, 464) = 464
GCD(1, 464) = ( 1 x 464 ) / 464
= 1 / 464
= 1
Step3:
LCM(1, 515) = 515
GCD(1, 515) = ( 1 x 515 ) / 515
= 1 / 515
= 1
So, Greatest Common Divisor of 398, 459, 464, 515 is 1
