Given numbers are 550, 685, 395, 253

The list of prime factors of all numbers are

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

Prime factors of 685 are 5 x 137

Prime factors of 395 are 5 x 79

Prime factors of 253 are 11 x 23

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

Given numbers are 550, 685, 395, 253

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

Apply this formula for all numbers.

Step1:

LCM(550, 685) = 75350

GCD(550, 685) = ( 550 x 685 ) / 75350

= 550 / 685

= 550

Step2:

LCM(5, 395) = 395

GCD(5, 395) = ( 5 x 395 ) / 395

= 5 / 395

= 5

Step3:

LCM(5, 253) = 1265

GCD(5, 253) = ( 5 x 253 ) / 1265

= 5 / 253

= 5

So, Greatest Common Divisor of 550, 685, 395, 253 is 1
