Given numbers are 154, 155, 434, 446

The list of prime factors of all numbers are

Prime factors of 154 are 2 x 7 x 11

Prime factors of 155 are 5 x 31

Prime factors of 434 are 2 x 7 x 31

Prime factors of 446 are 2 x 223

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

Given numbers are 154, 155, 434, 446

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

Apply this formula for all numbers.

Step1:

LCM(154, 155) = 23870

GCD(154, 155) = ( 154 x 155 ) / 23870

= 154 / 155

= 154

Step2:

LCM(1, 434) = 434

GCD(1, 434) = ( 1 x 434 ) / 434

= 1 / 434

= 1

Step3:

LCM(1, 446) = 446

GCD(1, 446) = ( 1 x 446 ) / 446

= 1 / 446

= 1

So, Greatest Common Divisor of 154, 155, 434, 446 is 1
