Given numbers are 811, 980, 538, 770

The list of prime factors of all numbers are

Prime factors of 811 are 811

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 538 are 2 x 269

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 811, 980, 538, 770

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

Apply this formula for all numbers.

Step1:

LCM(811, 980) = 794780

GCD(811, 980) = ( 811 x 980 ) / 794780

= 811 / 980

= 811

Step2:

LCM(1, 538) = 538

GCD(1, 538) = ( 1 x 538 ) / 538

= 1 / 538

= 1

Step3:

LCM(1, 770) = 770

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

= 1 / 770

= 1

So, Greatest Common Divisor of 811, 980, 538, 770 is 1
