Given numbers are 806, 812, 761, 644

The list of prime factors of all numbers are

Prime factors of 806 are 2 x 13 x 31

Prime factors of 812 are 2 x 2 x 7 x 29

Prime factors of 761 are 761

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 806, 812, 761, 644

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

Apply this formula for all numbers.

Step1:

LCM(806, 812) = 327236

GCD(806, 812) = ( 806 x 812 ) / 327236

= 806 / 812

= 806

Step2:

LCM(2, 761) = 1522

GCD(2, 761) = ( 2 x 761 ) / 1522

= 2 / 761

= 2

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 806, 812, 761, 644 is 1
