Given numbers are 515, 323, 720, 955
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 323) = 166345
GCD(515, 323) = ( 515 x 323 ) / 166345
= 515 / 323
= 515
Step2:
LCM(1, 720) = 720
GCD(1, 720) = ( 1 x 720 ) / 720
= 1 / 720
= 1
Step3:
LCM(1, 955) = 955
GCD(1, 955) = ( 1 x 955 ) / 955
= 1 / 955
= 1
So, Greatest Common Divisor of 515, 323, 720, 955 is 1
