Given numbers are 121, 625, 90, 440

The list of prime factors of all numbers are

Prime factors of 121 are 11 x 11

Prime factors of 625 are 5 x 5 x 5 x 5

Prime factors of 90 are 2 x 3 x 3 x 5

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

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

Given numbers are 121, 625, 90, 440

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

Apply this formula for all numbers.

Step1:

LCM(121, 625) = 75625

GCD(121, 625) = ( 121 x 625 ) / 75625

= 121 / 625

= 121

Step2:

LCM(1, 90) = 90

GCD(1, 90) = ( 1 x 90 ) / 90

= 1 / 90

= 1

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 121, 625, 90, 440 is 1
