Given numbers are 981, 155, 242, 867

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 155 are 5 x 31

Prime factors of 242 are 2 x 11 x 11

Prime factors of 867 are 3 x 17 x 17

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

Given numbers are 981, 155, 242, 867

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

Apply this formula for all numbers.

Step1:

LCM(981, 155) = 152055

GCD(981, 155) = ( 981 x 155 ) / 152055

= 981 / 155

= 981

Step2:

LCM(1, 242) = 242

GCD(1, 242) = ( 1 x 242 ) / 242

= 1 / 242

= 1

Step3:

LCM(1, 867) = 867

GCD(1, 867) = ( 1 x 867 ) / 867

= 1 / 867

= 1

So, Greatest Common Divisor of 981, 155, 242, 867 is 1
