Given numbers are 210, 775, 991, 406

The list of prime factors of all numbers are

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

Prime factors of 775 are 5 x 5 x 31

Prime factors of 991 are 991

Prime factors of 406 are 2 x 7 x 29

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

Given numbers are 210, 775, 991, 406

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

Apply this formula for all numbers.

Step1:

LCM(210, 775) = 32550

GCD(210, 775) = ( 210 x 775 ) / 32550

= 210 / 775

= 210

Step2:

LCM(5, 991) = 4955

GCD(5, 991) = ( 5 x 991 ) / 4955

= 5 / 991

= 5

Step3:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

So, Greatest Common Divisor of 210, 775, 991, 406 is 1
