Given numbers are 551, 135, 448, 840

The list of prime factors of all numbers are

Prime factors of 551 are 19 x 29

Prime factors of 135 are 3 x 3 x 3 x 5

Prime factors of 448 are 2 x 2 x 2 x 2 x 2 x 2 x 7

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

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

Given numbers are 551, 135, 448, 840

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

Apply this formula for all numbers.

Step1:

LCM(551, 135) = 74385

GCD(551, 135) = ( 551 x 135 ) / 74385

= 551 / 135

= 551

Step2:

LCM(1, 448) = 448

GCD(1, 448) = ( 1 x 448 ) / 448

= 1 / 448

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 551, 135, 448, 840 is 1
