Given numbers are 278, 801, 155, 444

The list of prime factors of all numbers are

Prime factors of 278 are 2 x 139

Prime factors of 801 are 3 x 3 x 89

Prime factors of 155 are 5 x 31

Prime factors of 444 are 2 x 2 x 3 x 37

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

Given numbers are 278, 801, 155, 444

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

Apply this formula for all numbers.

Step1:

LCM(278, 801) = 222678

GCD(278, 801) = ( 278 x 801 ) / 222678

= 278 / 801

= 278

Step2:

LCM(1, 155) = 155

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

= 1 / 155

= 1

Step3:

LCM(1, 444) = 444

GCD(1, 444) = ( 1 x 444 ) / 444

= 1 / 444

= 1

So, Greatest Common Divisor of 278, 801, 155, 444 is 1
