Given numbers are 425, 490, 121, 828

The list of prime factors of all numbers are

Prime factors of 425 are 5 x 5 x 17

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 121 are 11 x 11

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

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

Given numbers are 425, 490, 121, 828

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

Apply this formula for all numbers.

Step1:

LCM(425, 490) = 41650

GCD(425, 490) = ( 425 x 490 ) / 41650

= 425 / 490

= 425

Step2:

LCM(5, 121) = 605

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

= 5 / 121

= 5

Step3:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

So, Greatest Common Divisor of 425, 490, 121, 828 is 1
