Given numbers are 821, 972, 220, 367

The list of prime factors of all numbers are

Prime factors of 821 are 821

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

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

Prime factors of 367 are 367

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

Given numbers are 821, 972, 220, 367

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

Apply this formula for all numbers.

Step1:

LCM(821, 972) = 798012

GCD(821, 972) = ( 821 x 972 ) / 798012

= 821 / 972

= 821

Step2:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

Step3:

LCM(1, 367) = 367

GCD(1, 367) = ( 1 x 367 ) / 367

= 1 / 367

= 1

So, Greatest Common Divisor of 821, 972, 220, 367 is 1
