Given numbers are 561, 759, 620, 770

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 759 are 3 x 11 x 23

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

Prime factors of 770 are 2 x 5 x 7 x 11

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

Given numbers are 561, 759, 620, 770

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

Apply this formula for all numbers.

Step1:

LCM(561, 759) = 12903

GCD(561, 759) = ( 561 x 759 ) / 12903

= 561 / 759

= 561

Step2:

LCM(33, 620) = 20460

GCD(33, 620) = ( 33 x 620 ) / 20460

= 33 / 620

= 33

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 561, 759, 620, 770 is 1
