Given numbers are 821, 220, 664, 901

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 901 are 17 x 53

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

Given numbers are 821, 220, 664, 901

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

Apply this formula for all numbers.

Step1:

LCM(821, 220) = 180620

GCD(821, 220) = ( 821 x 220 ) / 180620

= 821 / 220

= 821

Step2:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

Step3:

LCM(1, 901) = 901

GCD(1, 901) = ( 1 x 901 ) / 901

= 1 / 901

= 1

So, Greatest Common Divisor of 821, 220, 664, 901 is 1
