Given numbers are 758, 690, 570, 491

The list of prime factors of all numbers are

Prime factors of 758 are 2 x 379

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

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 491 are 491

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

Given numbers are 758, 690, 570, 491

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

Apply this formula for all numbers.

Step1:

LCM(758, 690) = 261510

GCD(758, 690) = ( 758 x 690 ) / 261510

= 758 / 690

= 758

Step2:

LCM(2, 570) = 570

GCD(2, 570) = ( 2 x 570 ) / 570

= 2 / 570

= 2

Step3:

LCM(2, 491) = 982

GCD(2, 491) = ( 2 x 491 ) / 982

= 2 / 491

= 2

So, Greatest Common Divisor of 758, 690, 570, 491 is 1
