Therefore, GCD of numbers 55, 280, 898, 757 is 1

Given Input Data is 55, 280, 898, 757

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 55 is 5 x 11

Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7

Prime Factorization of 898 is 2 x 449

Prime Factorization of 757 is 757

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

Step1:

Let's calculate the GCD of first two numbers

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

LCM(55, 280) = 3080

GCD(55, 280) = ( 55 x 280 ) / 3080

GCD(55, 280) = 15400 / 3080

GCD(55, 280) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 898

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

LCM(5, 898) = 4490

GCD(5, 898) = ( 5 x 898 ) / 4490

GCD(5, 898) = 4490 / 4490

GCD(5, 898) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 757

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

LCM(1, 757) = 757

GCD(1, 757) = ( 1 x 757 ) / 757

GCD(1, 757) = 757 / 757

GCD(1, 757) = 1

GCD of 55, 280, 898, 757 is 1
