Given numbers are 781, 890, 806, 546

The list of prime factors of all numbers are

Prime factors of 781 are 11 x 71

Prime factors of 890 are 2 x 5 x 89

Prime factors of 806 are 2 x 13 x 31

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 781, 890, 806, 546

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

Apply this formula for all numbers.

Step1:

LCM(781, 890) = 695090

GCD(781, 890) = ( 781 x 890 ) / 695090

= 781 / 890

= 781

Step2:

LCM(1, 806) = 806

GCD(1, 806) = ( 1 x 806 ) / 806

= 1 / 806

= 1

Step3:

LCM(1, 546) = 546

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

= 1 / 546

= 1

So, Greatest Common Divisor of 781, 890, 806, 546 is 1
