Given numbers are 605, 407, 154, 402

The list of prime factors of all numbers are

Prime factors of 605 are 5 x 11 x 11

Prime factors of 407 are 11 x 37

Prime factors of 154 are 2 x 7 x 11

Prime factors of 402 are 2 x 3 x 67

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

Given numbers are 605, 407, 154, 402

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

Apply this formula for all numbers.

Step1:

LCM(605, 407) = 22385

GCD(605, 407) = ( 605 x 407 ) / 22385

= 605 / 407

= 605

Step2:

LCM(11, 154) = 154

GCD(11, 154) = ( 11 x 154 ) / 154

= 11 / 154

= 11

Step3:

LCM(11, 402) = 4422

GCD(11, 402) = ( 11 x 402 ) / 4422

= 11 / 402

= 11

So, Greatest Common Divisor of 605, 407, 154, 402 is 1
