Given numbers are 478, 505, 61

The list of prime factors of all numbers are

Prime factors of 478 are 2 x 239

Prime factors of 505 are 5 x 101

Prime factors of 61 are 61

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

Given numbers are 478, 505, 61

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

Apply this formula for all numbers.

Step1:

LCM(478, 505) = 241390

GCD(478, 505) = ( 478 x 505 ) / 241390

= 478 / 505

= 478

Step2:

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

= 1 / 61

= 1

So, Greatest Common Divisor of 478, 505, 61 is 1
