Given numbers are 622, 420, 347, 981

The list of prime factors of all numbers are

Prime factors of 622 are 2 x 311

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 347 are 347

Prime factors of 981 are 3 x 3 x 109

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

Given numbers are 622, 420, 347, 981

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

Apply this formula for all numbers.

Step1:

LCM(622, 420) = 130620

GCD(622, 420) = ( 622 x 420 ) / 130620

= 622 / 420

= 622

Step2:

LCM(2, 347) = 694

GCD(2, 347) = ( 2 x 347 ) / 694

= 2 / 347

= 2

Step3:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

So, Greatest Common Divisor of 622, 420, 347, 981 is 1
