Given numbers are 688, 338, 215, 146

The list of prime factors of all numbers are

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 338 are 2 x 13 x 13

Prime factors of 215 are 5 x 43

Prime factors of 146 are 2 x 73

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

Given numbers are 688, 338, 215, 146

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

Apply this formula for all numbers.

Step1:

LCM(688, 338) = 116272

GCD(688, 338) = ( 688 x 338 ) / 116272

= 688 / 338

= 688

Step2:

LCM(2, 215) = 430

GCD(2, 215) = ( 2 x 215 ) / 430

= 2 / 215

= 2

Step3:

LCM(1, 146) = 146

GCD(1, 146) = ( 1 x 146 ) / 146

= 1 / 146

= 1

So, Greatest Common Divisor of 688, 338, 215, 146 is 1
