Given numbers are 516, 493, 12, 780

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

Apply this formula for all numbers.

Step1:

LCM(516, 493) = 254388

GCD(516, 493) = ( 516 x 493 ) / 254388

= 516 / 493

= 516

Step2:

LCM(1, 12) = 12

GCD(1, 12) = ( 1 x 12 ) / 12

= 1 / 12

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 516, 493, 12, 780 is 1
