Given numbers are 981, 670, 550, 561

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 670 are 2 x 5 x 67

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 561 are 3 x 11 x 17

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

Given numbers are 981, 670, 550, 561

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

Apply this formula for all numbers.

Step1:

LCM(981, 670) = 657270

GCD(981, 670) = ( 981 x 670 ) / 657270

= 981 / 670

= 981

Step2:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 981, 670, 550, 561 is 1
