Given numbers are 215, 764, 354, 168

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 764 are 2 x 2 x 191

Prime factors of 354 are 2 x 3 x 59

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

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

Given numbers are 215, 764, 354, 168

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

Apply this formula for all numbers.

Step1:

LCM(215, 764) = 164260

GCD(215, 764) = ( 215 x 764 ) / 164260

= 215 / 764

= 215

Step2:

LCM(1, 354) = 354

GCD(1, 354) = ( 1 x 354 ) / 354

= 1 / 354

= 1

Step3:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

So, Greatest Common Divisor of 215, 764, 354, 168 is 1
