We found the divisors of 643, 511, 60, 786 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 643, 511, 60, 786 is 1.

Therefore, GCD of numbers 643, 511, 60, 786 is 1

Given Input Data is 643, 511, 60, 786

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

Prime Factorization of 643 is 643

Prime Factorization of 511 is 7 x 73

Prime Factorization of 60 is 2 x 2 x 3 x 5

Prime Factorization of 786 is 2 x 3 x 131

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(643, 511) = 328573

GCD(643, 511) = ( 643 x 511 ) / 328573

GCD(643, 511) = 328573 / 328573

GCD(643, 511) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 60

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

LCM(1, 60) = 60

GCD(1, 60) = ( 1 x 60 ) / 60

GCD(1, 60) = 60 / 60

GCD(1, 60) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 786

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

LCM(1, 786) = 786

GCD(1, 786) = ( 1 x 786 ) / 786

GCD(1, 786) = 786 / 786

GCD(1, 786) = 1

GCD of 643, 511, 60, 786 is 1
