Given numbers are 310, 815, 578, 783

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

Apply this formula for all numbers.

Step1:

LCM(310, 815) = 50530

GCD(310, 815) = ( 310 x 815 ) / 50530

= 310 / 815

= 310

Step2:

LCM(5, 578) = 2890

GCD(5, 578) = ( 5 x 578 ) / 2890

= 5 / 578

= 5

Step3:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

So, Greatest Common Divisor of 310, 815, 578, 783 is 1
