Given numbers are 561, 619, 750, 686

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 619 are 619

Prime factors of 750 are 2 x 3 x 5 x 5 x 5

Prime factors of 686 are 2 x 7 x 7 x 7

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

Given numbers are 561, 619, 750, 686

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

Apply this formula for all numbers.

Step1:

LCM(561, 619) = 347259

GCD(561, 619) = ( 561 x 619 ) / 347259

= 561 / 619

= 561

Step2:

LCM(1, 750) = 750

GCD(1, 750) = ( 1 x 750 ) / 750

= 1 / 750

= 1

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 561, 619, 750, 686 is 1
