Given numbers are 781, 548, 517, 486

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

Apply this formula for all numbers.

Step1:

LCM(781, 548) = 427988

GCD(781, 548) = ( 781 x 548 ) / 427988

= 781 / 548

= 781

Step2:

LCM(1, 517) = 517

GCD(1, 517) = ( 1 x 517 ) / 517

= 1 / 517

= 1

Step3:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

So, Greatest Common Divisor of 781, 548, 517, 486 is 1
