Given numbers are 703, 780, 513, 690

The list of prime factors of all numbers are

Prime factors of 703 are 19 x 37

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 513 are 3 x 3 x 3 x 19

Prime factors of 690 are 2 x 3 x 5 x 23

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

Given numbers are 703, 780, 513, 690

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

Apply this formula for all numbers.

Step1:

LCM(703, 780) = 548340

GCD(703, 780) = ( 703 x 780 ) / 548340

= 703 / 780

= 703

Step2:

LCM(1, 513) = 513

GCD(1, 513) = ( 1 x 513 ) / 513

= 1 / 513

= 1

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 703, 780, 513, 690 is 1
