Given numbers are 783, 624, 615, 813

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

Apply this formula for all numbers.

Step1:

LCM(783, 624) = 162864

GCD(783, 624) = ( 783 x 624 ) / 162864

= 783 / 624

= 783

Step2:

LCM(3, 615) = 615

GCD(3, 615) = ( 3 x 615 ) / 615

= 3 / 615

= 3

Step3:

LCM(3, 813) = 813

GCD(3, 813) = ( 3 x 813 ) / 813

= 3 / 813

= 3

So, Greatest Common Divisor of 783, 624, 615, 813 is 3
