Given numbers are 781, 815, 542, 483

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

Apply this formula for all numbers.

Step1:

LCM(781, 815) = 636515

GCD(781, 815) = ( 781 x 815 ) / 636515

= 781 / 815

= 781

Step2:

LCM(1, 542) = 542

GCD(1, 542) = ( 1 x 542 ) / 542

= 1 / 542

= 1

Step3:

LCM(1, 483) = 483

GCD(1, 483) = ( 1 x 483 ) / 483

= 1 / 483

= 1

So, Greatest Common Divisor of 781, 815, 542, 483 is 1
