Therefore, GCD of numbers 780, 561, 708, 152 is 1

Given Input Data is 780, 561, 708, 152

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

Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13

Prime Factorization of 561 is 3 x 11 x 17

Prime Factorization of 708 is 2 x 2 x 3 x 59

Prime Factorization of 152 is 2 x 2 x 2 x 19

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(780, 561) = 145860

GCD(780, 561) = ( 780 x 561 ) / 145860

GCD(780, 561) = 437580 / 145860

GCD(780, 561) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 708

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

LCM(3, 708) = 708

GCD(3, 708) = ( 3 x 708 ) / 708

GCD(3, 708) = 2124 / 708

GCD(3, 708) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 152

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

LCM(3, 152) = 456

GCD(3, 152) = ( 3 x 152 ) / 456

GCD(3, 152) = 456 / 456

GCD(3, 152) = 1

GCD of 780, 561, 708, 152 is 1
