Given numbers are 221, 705, 945, 822

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 705 are 3 x 5 x 47

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 822 are 2 x 3 x 137

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

Given numbers are 221, 705, 945, 822

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

Apply this formula for all numbers.

Step1:

LCM(221, 705) = 155805

GCD(221, 705) = ( 221 x 705 ) / 155805

= 221 / 705

= 221

Step2:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

Step3:

LCM(1, 822) = 822

GCD(1, 822) = ( 1 x 822 ) / 822

= 1 / 822

= 1

So, Greatest Common Divisor of 221, 705, 945, 822 is 1
