Given numbers are 770, 390, 491, 553

The list of prime factors of all numbers are

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

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 491 are 491

Prime factors of 553 are 7 x 79

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

Given numbers are 770, 390, 491, 553

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

Apply this formula for all numbers.

Step1:

LCM(770, 390) = 30030

GCD(770, 390) = ( 770 x 390 ) / 30030

= 770 / 390

= 770

Step2:

LCM(10, 491) = 4910

GCD(10, 491) = ( 10 x 491 ) / 4910

= 10 / 491

= 10

Step3:

LCM(1, 553) = 553

GCD(1, 553) = ( 1 x 553 ) / 553

= 1 / 553

= 1

So, Greatest Common Divisor of 770, 390, 491, 553 is 1
