Given numbers are 642, 260, 335, 126

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 335 are 5 x 67

Prime factors of 126 are 2 x 3 x 3 x 7

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

Given numbers are 642, 260, 335, 126

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

Apply this formula for all numbers.

Step1:

LCM(642, 260) = 83460

GCD(642, 260) = ( 642 x 260 ) / 83460

= 642 / 260

= 642

Step2:

LCM(2, 335) = 670

GCD(2, 335) = ( 2 x 335 ) / 670

= 2 / 335

= 2

Step3:

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

= 1 / 126

= 1

So, Greatest Common Divisor of 642, 260, 335, 126 is 1
