Given numbers are 305, 432, 642, 214

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 642 are 2 x 3 x 107

Prime factors of 214 are 2 x 107

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

Given numbers are 305, 432, 642, 214

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

Apply this formula for all numbers.

Step1:

LCM(305, 432) = 131760

GCD(305, 432) = ( 305 x 432 ) / 131760

= 305 / 432

= 305

Step2:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

Step3:

LCM(1, 214) = 214

GCD(1, 214) = ( 1 x 214 ) / 214

= 1 / 214

= 1

So, Greatest Common Divisor of 305, 432, 642, 214 is 1
