Given numbers are 210, 945, 770, 388

The list of prime factors of all numbers are

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

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 388 are 2 x 2 x 97

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

Given numbers are 210, 945, 770, 388

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

Apply this formula for all numbers.

Step1:

LCM(210, 945) = 1890

GCD(210, 945) = ( 210 x 945 ) / 1890

= 210 / 945

= 210

Step2:

LCM(105, 770) = 2310

GCD(105, 770) = ( 105 x 770 ) / 2310

= 105 / 770

= 105

Step3:

LCM(35, 388) = 13580

GCD(35, 388) = ( 35 x 388 ) / 13580

= 35 / 388

= 35

So, Greatest Common Divisor of 210, 945, 770, 388 is 1
