Make use of GCD Calculator to determine the Greatest Common Divisor of 651, 647, 70, 660 i.e. 1 largest integer that divides all the numbers equally.
GCD of 651, 647, 70, 660 is 1
GCD(651, 647, 70, 660) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 651, 647, 70, 660 is 1
GCD(651, 647, 70, 660) = 1
Given Input numbers are 651, 647, 70, 660
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 5, 7, 10, 14, 35, 70
Divisors of 660
List of positive integer divisors of 660 that divides 660 without a remainder.
1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
Greatest Common Divisior
We found the divisors of 651, 647, 70, 660 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 651, 647, 70, 660 is 1.
Therefore, GCD of numbers 651, 647, 70, 660 is 1
Given Input Data is 651, 647, 70, 660
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 651 is 3 x 7 x 31
Prime Factorization of 647 is 647
Prime Factorization of 70 is 2 x 5 x 7
Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11
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(651, 647) = 421197
GCD(651, 647) = ( 651 x 647 ) / 421197
GCD(651, 647) = 421197 / 421197
GCD(651, 647) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 70
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 70) = 70
GCD(1, 70) = ( 1 x 70 ) / 70
GCD(1, 70) = 70 / 70
GCD(1, 70) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 660
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 660) = 660
GCD(1, 660) = ( 1 x 660 ) / 660
GCD(1, 660) = 660 / 660
GCD(1, 660) = 1
GCD of 651, 647, 70, 660 is 1
