Given numbers are 217, 106, 285, 974

The list of prime factors of all numbers are

Prime factors of 217 are 7 x 31

Prime factors of 106 are 2 x 53

Prime factors of 285 are 3 x 5 x 19

Prime factors of 974 are 2 x 487

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

Given numbers are 217, 106, 285, 974

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

Apply this formula for all numbers.

Step1:

LCM(217, 106) = 23002

GCD(217, 106) = ( 217 x 106 ) / 23002

= 217 / 106

= 217

Step2:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

Step3:

LCM(1, 974) = 974

GCD(1, 974) = ( 1 x 974 ) / 974

= 1 / 974

= 1

So, Greatest Common Divisor of 217, 106, 285, 974 is 1
