Given numbers are 620, 225, 71, 635

The list of prime factors of all numbers are

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 225 are 3 x 3 x 5 x 5

Prime factors of 71 are 71

Prime factors of 635 are 5 x 127

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

Given numbers are 620, 225, 71, 635

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

Apply this formula for all numbers.

Step1:

LCM(620, 225) = 27900

GCD(620, 225) = ( 620 x 225 ) / 27900

= 620 / 225

= 620

Step2:

LCM(5, 71) = 355

GCD(5, 71) = ( 5 x 71 ) / 355

= 5 / 71

= 5

Step3:

LCM(1, 635) = 635

GCD(1, 635) = ( 1 x 635 ) / 635

= 1 / 635

= 1

So, Greatest Common Divisor of 620, 225, 71, 635 is 1
