Given numbers are 650, 120, 658, 561

The list of prime factors of all numbers are

Prime factors of 650 are 2 x 5 x 5 x 13

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 658 are 2 x 7 x 47

Prime factors of 561 are 3 x 11 x 17

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

Given numbers are 650, 120, 658, 561

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

Apply this formula for all numbers.

Step1:

LCM(650, 120) = 7800

GCD(650, 120) = ( 650 x 120 ) / 7800

= 650 / 120

= 650

Step2:

LCM(10, 658) = 3290

GCD(10, 658) = ( 10 x 658 ) / 3290

= 10 / 658

= 10

Step3:

LCM(2, 561) = 1122

GCD(2, 561) = ( 2 x 561 ) / 1122

= 2 / 561

= 2

So, Greatest Common Divisor of 650, 120, 658, 561 is 1
