Given numbers are 642, 564, 514, 209

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 564 are 2 x 2 x 3 x 47

Prime factors of 514 are 2 x 257

Prime factors of 209 are 11 x 19

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

Given numbers are 642, 564, 514, 209

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

Apply this formula for all numbers.

Step1:

LCM(642, 564) = 60348

GCD(642, 564) = ( 642 x 564 ) / 60348

= 642 / 564

= 642

Step2:

LCM(6, 514) = 1542

GCD(6, 514) = ( 6 x 514 ) / 1542

= 6 / 514

= 6

Step3:

LCM(2, 209) = 418

GCD(2, 209) = ( 2 x 209 ) / 418

= 2 / 209

= 2

So, Greatest Common Divisor of 642, 564, 514, 209 is 1
