Given numbers are 615, 115, 623, 813

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(615, 115) = 14145

GCD(615, 115) = ( 615 x 115 ) / 14145

= 615 / 115

= 615

Step2:

LCM(5, 623) = 3115

GCD(5, 623) = ( 5 x 623 ) / 3115

= 5 / 623

= 5

Step3:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 615, 115, 623, 813 is 1
