Given numbers are 210, 176, 440, 921

The list of prime factors of all numbers are

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 176 are 2 x 2 x 2 x 2 x 11

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

Prime factors of 921 are 3 x 307

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

Given numbers are 210, 176, 440, 921

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

Apply this formula for all numbers.

Step1:

LCM(210, 176) = 18480

GCD(210, 176) = ( 210 x 176 ) / 18480

= 210 / 176

= 210

Step2:

LCM(2, 440) = 440

GCD(2, 440) = ( 2 x 440 ) / 440

= 2 / 440

= 2

Step3:

LCM(2, 921) = 1842

GCD(2, 921) = ( 2 x 921 ) / 1842

= 2 / 921

= 2

So, Greatest Common Divisor of 210, 176, 440, 921 is 1
