Given numbers are 220, 225, 121, 635

The list of prime factors of all numbers are

Prime factors of 220 are 2 x 2 x 5 x 11

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

Prime factors of 121 are 11 x 11

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 220, 225, 121, 635

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

Apply this formula for all numbers.

Step1:

LCM(220, 225) = 9900

GCD(220, 225) = ( 220 x 225 ) / 9900

= 220 / 225

= 220

Step2:

LCM(5, 121) = 605

GCD(5, 121) = ( 5 x 121 ) / 605

= 5 / 121

= 5

Step3:

LCM(1, 635) = 635

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

= 1 / 635

= 1

So, Greatest Common Divisor of 220, 225, 121, 635 is 1
