Given numbers are 800, 440, 615, 665

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

Apply this formula for all numbers.

Step1:

LCM(800, 440) = 8800

GCD(800, 440) = ( 800 x 440 ) / 8800

= 800 / 440

= 800

Step2:

LCM(40, 615) = 4920

GCD(40, 615) = ( 40 x 615 ) / 4920

= 40 / 615

= 40

Step3:

LCM(5, 665) = 665

GCD(5, 665) = ( 5 x 665 ) / 665

= 5 / 665

= 5

So, Greatest Common Divisor of 800, 440, 615, 665 is 5
