Given numbers are 806, 148, 620, 581

The list of prime factors of all numbers are

Prime factors of 806 are 2 x 13 x 31

Prime factors of 148 are 2 x 2 x 37

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 581 are 7 x 83

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

Given numbers are 806, 148, 620, 581

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

Apply this formula for all numbers.

Step1:

LCM(806, 148) = 59644

GCD(806, 148) = ( 806 x 148 ) / 59644

= 806 / 148

= 806

Step2:

LCM(2, 620) = 620

GCD(2, 620) = ( 2 x 620 ) / 620

= 2 / 620

= 2

Step3:

LCM(2, 581) = 1162

GCD(2, 581) = ( 2 x 581 ) / 1162

= 2 / 581

= 2

So, Greatest Common Divisor of 806, 148, 620, 581 is 1
