Given numbers are 215, 140, 97, 814

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 97 are 97

Prime factors of 814 are 2 x 11 x 37

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

Given numbers are 215, 140, 97, 814

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

Apply this formula for all numbers.

Step1:

LCM(215, 140) = 6020

GCD(215, 140) = ( 215 x 140 ) / 6020

= 215 / 140

= 215

Step2:

LCM(5, 97) = 485

GCD(5, 97) = ( 5 x 97 ) / 485

= 5 / 97

= 5

Step3:

LCM(1, 814) = 814

GCD(1, 814) = ( 1 x 814 ) / 814

= 1 / 814

= 1

So, Greatest Common Divisor of 215, 140, 97, 814 is 1
