Given numbers are 402, 991, 110, 770

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 991 are 991

Prime factors of 110 are 2 x 5 x 11

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 402, 991, 110, 770

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

Apply this formula for all numbers.

Step1:

LCM(402, 991) = 398382

GCD(402, 991) = ( 402 x 991 ) / 398382

= 402 / 991

= 402

Step2:

LCM(1, 110) = 110

GCD(1, 110) = ( 1 x 110 ) / 110

= 1 / 110

= 1

Step3:

LCM(1, 770) = 770

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

= 1 / 770

= 1

So, Greatest Common Divisor of 402, 991, 110, 770 is 1
