Given numbers are 130, 178, 434, 989

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 178 are 2 x 89

Prime factors of 434 are 2 x 7 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 130, 178, 434, 989

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

Apply this formula for all numbers.

Step1:

LCM(130, 178) = 11570

GCD(130, 178) = ( 130 x 178 ) / 11570

= 130 / 178

= 130

Step2:

LCM(2, 434) = 434

GCD(2, 434) = ( 2 x 434 ) / 434

= 2 / 434

= 2

Step3:

LCM(2, 989) = 1978

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

= 2 / 989

= 2

So, Greatest Common Divisor of 130, 178, 434, 989 is 1
