Given numbers are 505, 412, 858, 972

The list of prime factors of all numbers are

Prime factors of 505 are 5 x 101

Prime factors of 412 are 2 x 2 x 103

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

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

Given numbers are 505, 412, 858, 972

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

Apply this formula for all numbers.

Step1:

LCM(505, 412) = 208060

GCD(505, 412) = ( 505 x 412 ) / 208060

= 505 / 412

= 505

Step2:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

Step3:

LCM(1, 972) = 972

GCD(1, 972) = ( 1 x 972 ) / 972

= 1 / 972

= 1

So, Greatest Common Divisor of 505, 412, 858, 972 is 1
