Given numbers are 642, 206, 679, 936

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 206 are 2 x 103

Prime factors of 679 are 7 x 97

Prime factors of 936 are 2 x 2 x 2 x 3 x 3 x 13

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

Given numbers are 642, 206, 679, 936

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

Apply this formula for all numbers.

Step1:

LCM(642, 206) = 66126

GCD(642, 206) = ( 642 x 206 ) / 66126

= 642 / 206

= 642

Step2:

LCM(2, 679) = 1358

GCD(2, 679) = ( 2 x 679 ) / 1358

= 2 / 679

= 2

Step3:

LCM(1, 936) = 936

GCD(1, 936) = ( 1 x 936 ) / 936

= 1 / 936

= 1

So, Greatest Common Divisor of 642, 206, 679, 936 is 1
