Given numbers are 806, 761, 864, 647

The list of prime factors of all numbers are

Prime factors of 806 are 2 x 13 x 31

Prime factors of 761 are 761

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 647 are 647

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

Given numbers are 806, 761, 864, 647

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

Apply this formula for all numbers.

Step1:

LCM(806, 761) = 613366

GCD(806, 761) = ( 806 x 761 ) / 613366

= 806 / 761

= 806

Step2:

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

= 1 / 864

= 1

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 806, 761, 864, 647 is 1
