Make use of GCD Calculator to determine the Greatest Common Divisor of 155, 670, 61, 591 i.e. 1 largest integer that divides all the numbers equally.
GCD of 155, 670, 61, 591 is 1
GCD(155, 670, 61, 591) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 155, 670, 61, 591 is 1
GCD(155, 670, 61, 591) = 1
Given Input numbers are 155, 670, 61, 591
To find the GCD of numbers using factoring list out all the divisors of each number

1, 3, 197, 591
Greatest Common Divisior
We found the divisors of 155, 670, 61, 591 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 155, 670, 61, 591 is 1.
Therefore, GCD of numbers 155, 670, 61, 591 is 1
Given Input Data is 155, 670, 61, 591
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 155 is 5 x 31
Prime Factorization of 670 is 2 x 5 x 67
Prime Factorization of 61 is 61
Prime Factorization of 591 is 3 x 197
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(155, 670) = 20770
GCD(155, 670) = ( 155 x 670 ) / 20770
GCD(155, 670) = 103850 / 20770
GCD(155, 670) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 61
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 61) = 305
GCD(5, 61) = ( 5 x 61 ) / 305
GCD(5, 61) = 305 / 305
GCD(5, 61) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 591
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 591) = 591
GCD(1, 591) = ( 1 x 591 ) / 591
GCD(1, 591) = 591 / 591
GCD(1, 591) = 1
GCD of 155, 670, 61, 591 is 1
