Given numbers are 721, 505, 783, 770

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 505 are 5 x 101

Prime factors of 783 are 3 x 3 x 3 x 29

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 721, 505, 783, 770

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

Apply this formula for all numbers.

Step1:

LCM(721, 505) = 364105

GCD(721, 505) = ( 721 x 505 ) / 364105

= 721 / 505

= 721

Step2:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

Step3:

LCM(1, 770) = 770

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

= 1 / 770

= 1

So, Greatest Common Divisor of 721, 505, 783, 770 is 1
