Given numbers are 313, 805, 20, 619

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

Apply this formula for all numbers.

Step1:

LCM(313, 805) = 251965

GCD(313, 805) = ( 313 x 805 ) / 251965

= 313 / 805

= 313

Step2:

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

= 1 / 20

= 1

Step3:

LCM(1, 619) = 619

GCD(1, 619) = ( 1 x 619 ) / 619

= 1 / 619

= 1

So, Greatest Common Divisor of 313, 805, 20, 619 is 1
