Given numbers are 868, 984, 278, 989

The list of prime factors of all numbers are

Prime factors of 868 are 2 x 2 x 7 x 31

Prime factors of 984 are 2 x 2 x 2 x 3 x 41

Prime factors of 278 are 2 x 139

Prime factors of 989 are 23 x 43

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

Given numbers are 868, 984, 278, 989

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

Apply this formula for all numbers.

Step1:

LCM(868, 984) = 213528

GCD(868, 984) = ( 868 x 984 ) / 213528

= 868 / 984

= 868

Step2:

LCM(4, 278) = 556

GCD(4, 278) = ( 4 x 278 ) / 556

= 4 / 278

= 4

Step3:

LCM(2, 989) = 1978

GCD(2, 989) = ( 2 x 989 ) / 1978

= 2 / 989

= 2

So, Greatest Common Divisor of 868, 984, 278, 989 is 1
