Given numbers are 615, 115, 153, 915

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, 153) = 765

GCD(5, 153) = ( 5 x 153 ) / 765

= 5 / 153

= 5

Step3:

LCM(1, 915) = 915

GCD(1, 915) = ( 1 x 915 ) / 915

= 1 / 915

= 1

So, Greatest Common Divisor of 615, 115, 153, 915 is 1
