Given numbers are 210, 911, 690, 811

The list of prime factors of all numbers are

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

Prime factors of 911 are 911

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 811 are 811

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

Given numbers are 210, 911, 690, 811

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

Apply this formula for all numbers.

Step1:

LCM(210, 911) = 191310

GCD(210, 911) = ( 210 x 911 ) / 191310

= 210 / 911

= 210

Step2:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

Step3:

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

= 1 / 811

= 1

So, Greatest Common Divisor of 210, 911, 690, 811 is 1
