Given numbers are 638, 606, 840, 565

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 606 are 2 x 3 x 101

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 565 are 5 x 113

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

Given numbers are 638, 606, 840, 565

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

Apply this formula for all numbers.

Step1:

LCM(638, 606) = 193314

GCD(638, 606) = ( 638 x 606 ) / 193314

= 638 / 606

= 638

Step2:

LCM(2, 840) = 840

GCD(2, 840) = ( 2 x 840 ) / 840

= 2 / 840

= 2

Step3:

LCM(2, 565) = 1130

GCD(2, 565) = ( 2 x 565 ) / 1130

= 2 / 565

= 2

So, Greatest Common Divisor of 638, 606, 840, 565 is 1
