Given numbers are 642, 362, 451, 216

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 362 are 2 x 181

Prime factors of 451 are 11 x 41

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

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

Given numbers are 642, 362, 451, 216

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

Apply this formula for all numbers.

Step1:

LCM(642, 362) = 116202

GCD(642, 362) = ( 642 x 362 ) / 116202

= 642 / 362

= 642

Step2:

LCM(2, 451) = 902

GCD(2, 451) = ( 2 x 451 ) / 902

= 2 / 451

= 2

Step3:

LCM(1, 216) = 216

GCD(1, 216) = ( 1 x 216 ) / 216

= 1 / 216

= 1

So, Greatest Common Divisor of 642, 362, 451, 216 is 1
