Given numbers are 130, 731, 278, 550

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 731 are 17 x 43

Prime factors of 278 are 2 x 139

Prime factors of 550 are 2 x 5 x 5 x 11

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

Given numbers are 130, 731, 278, 550

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

Apply this formula for all numbers.

Step1:

LCM(130, 731) = 95030

GCD(130, 731) = ( 130 x 731 ) / 95030

= 130 / 731

= 130

Step2:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

Step3:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

So, Greatest Common Divisor of 130, 731, 278, 550 is 1
