Given numbers are 650, 158, 645, 581

The list of prime factors of all numbers are

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

Prime factors of 158 are 2 x 79

Prime factors of 645 are 3 x 5 x 43

Prime factors of 581 are 7 x 83

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

Given numbers are 650, 158, 645, 581

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

Apply this formula for all numbers.

Step1:

LCM(650, 158) = 51350

GCD(650, 158) = ( 650 x 158 ) / 51350

= 650 / 158

= 650

Step2:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

Step3:

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

= 1 / 581

= 1

So, Greatest Common Divisor of 650, 158, 645, 581 is 1
