Given numbers are 981, 862, 978, 630

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 862 are 2 x 431

Prime factors of 978 are 2 x 3 x 163

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 981, 862, 978, 630

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

Apply this formula for all numbers.

Step1:

LCM(981, 862) = 845622

GCD(981, 862) = ( 981 x 862 ) / 845622

= 981 / 862

= 981

Step2:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 981, 862, 978, 630 is 1
