Given numbers are 490, 234, 445, 155

The list of prime factors of all numbers are

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 234 are 2 x 3 x 3 x 13

Prime factors of 445 are 5 x 89

Prime factors of 155 are 5 x 31

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

Given numbers are 490, 234, 445, 155

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

Apply this formula for all numbers.

Step1:

LCM(490, 234) = 57330

GCD(490, 234) = ( 490 x 234 ) / 57330

= 490 / 234

= 490

Step2:

LCM(2, 445) = 890

GCD(2, 445) = ( 2 x 445 ) / 890

= 2 / 445

= 2

Step3:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

So, Greatest Common Divisor of 490, 234, 445, 155 is 1
