Given numbers are 770, 261, 909, 401

The list of prime factors of all numbers are

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

Prime factors of 261 are 3 x 3 x 29

Prime factors of 909 are 3 x 3 x 101

Prime factors of 401 are 401

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

Given numbers are 770, 261, 909, 401

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

Apply this formula for all numbers.

Step1:

LCM(770, 261) = 200970

GCD(770, 261) = ( 770 x 261 ) / 200970

= 770 / 261

= 770

Step2:

LCM(1, 909) = 909

GCD(1, 909) = ( 1 x 909 ) / 909

= 1 / 909

= 1

Step3:

LCM(1, 401) = 401

GCD(1, 401) = ( 1 x 401 ) / 401

= 1 / 401

= 1

So, Greatest Common Divisor of 770, 261, 909, 401 is 1
