Given numbers are 155, 361, 246, 442

The list of prime factors of all numbers are

Prime factors of 155 are 5 x 31

Prime factors of 361 are 19 x 19

Prime factors of 246 are 2 x 3 x 41

Prime factors of 442 are 2 x 13 x 17

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

Given numbers are 155, 361, 246, 442

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

Apply this formula for all numbers.

Step1:

LCM(155, 361) = 55955

GCD(155, 361) = ( 155 x 361 ) / 55955

= 155 / 361

= 155

Step2:

LCM(1, 246) = 246

GCD(1, 246) = ( 1 x 246 ) / 246

= 1 / 246

= 1

Step3:

LCM(1, 442) = 442

GCD(1, 442) = ( 1 x 442 ) / 442

= 1 / 442

= 1

So, Greatest Common Divisor of 155, 361, 246, 442 is 1
