Given numbers are 898, 998, 642, 981

The list of prime factors of all numbers are

Prime factors of 898 are 2 x 449

Prime factors of 998 are 2 x 499

Prime factors of 642 are 2 x 3 x 107

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 898, 998, 642, 981

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

Apply this formula for all numbers.

Step1:

LCM(898, 998) = 448102

GCD(898, 998) = ( 898 x 998 ) / 448102

= 898 / 998

= 898

Step2:

LCM(2, 642) = 642

GCD(2, 642) = ( 2 x 642 ) / 642

= 2 / 642

= 2

Step3:

LCM(2, 981) = 1962

GCD(2, 981) = ( 2 x 981 ) / 1962

= 2 / 981

= 2

So, Greatest Common Divisor of 898, 998, 642, 981 is 1
