Given numbers are 571, 612, 690, 247

The list of prime factors of all numbers are

Prime factors of 571 are 571

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

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

Prime factors of 247 are 13 x 19

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

Given numbers are 571, 612, 690, 247

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

Apply this formula for all numbers.

Step1:

LCM(571, 612) = 349452

GCD(571, 612) = ( 571 x 612 ) / 349452

= 571 / 612

= 571

Step2:

LCM(1, 690) = 690

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

= 1 / 690

= 1

Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

So, Greatest Common Divisor of 571, 612, 690, 247 is 1
