Given numbers are 415, 440, 521, 660

The list of prime factors of all numbers are

Prime factors of 415 are 5 x 83

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

Prime factors of 521 are 521

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Given numbers are 415, 440, 521, 660

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

Apply this formula for all numbers.

Step1:

LCM(415, 440) = 36520

GCD(415, 440) = ( 415 x 440 ) / 36520

= 415 / 440

= 415

Step2:

LCM(5, 521) = 2605

GCD(5, 521) = ( 5 x 521 ) / 2605

= 5 / 521

= 5

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 415, 440, 521, 660 is 1
