Given numbers are 605, 860, 781, 546

The list of prime factors of all numbers are

Prime factors of 605 are 5 x 11 x 11

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 781 are 11 x 71

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

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

Given numbers are 605, 860, 781, 546

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

Apply this formula for all numbers.

Step1:

LCM(605, 860) = 104060

GCD(605, 860) = ( 605 x 860 ) / 104060

= 605 / 860

= 605

Step2:

LCM(5, 781) = 3905

GCD(5, 781) = ( 5 x 781 ) / 3905

= 5 / 781

= 5

Step3:

LCM(1, 546) = 546

GCD(1, 546) = ( 1 x 546 ) / 546

= 1 / 546

= 1

So, Greatest Common Divisor of 605, 860, 781, 546 is 1
