Given numbers are 253, 840, 775, 989

The list of prime factors of all numbers are

Prime factors of 253 are 11 x 23

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 775 are 5 x 5 x 31

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 253, 840, 775, 989

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

Apply this formula for all numbers.

Step1:

LCM(253, 840) = 212520

GCD(253, 840) = ( 253 x 840 ) / 212520

= 253 / 840

= 253

Step2:

LCM(1, 775) = 775

GCD(1, 775) = ( 1 x 775 ) / 775

= 1 / 775

= 1

Step3:

LCM(1, 989) = 989

GCD(1, 989) = ( 1 x 989 ) / 989

= 1 / 989

= 1

So, Greatest Common Divisor of 253, 840, 775, 989 is 1
