Given numbers are 781, 546, 559, 630

The list of prime factors of all numbers are

Prime factors of 781 are 11 x 71

Prime factors of 546 are 2 x 3 x 7 x 13

Prime factors of 559 are 13 x 43

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 781, 546, 559, 630

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

Apply this formula for all numbers.

Step1:

LCM(781, 546) = 426426

GCD(781, 546) = ( 781 x 546 ) / 426426

= 781 / 546

= 781

Step2:

LCM(1, 559) = 559

GCD(1, 559) = ( 1 x 559 ) / 559

= 1 / 559

= 1

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 781, 546, 559, 630 is 1
