Make use of GCD Calculator to determine the Greatest Common Divisor of 658, 721, 62, 128 i.e. 1 largest integer that divides all the numbers equally.
GCD of 658, 721, 62, 128 is 1
GCD(658, 721, 62, 128) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 658, 721, 62, 128 is 1
GCD(658, 721, 62, 128) = 1
Given Input numbers are 658, 721, 62, 128
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 4, 8, 16, 32, 64, 128
Greatest Common Divisior
We found the divisors of 658, 721, 62, 128 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 658, 721, 62, 128 is 1.
Therefore, GCD of numbers 658, 721, 62, 128 is 1
Given Input Data is 658, 721, 62, 128
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 658 is 2 x 7 x 47
Prime Factorization of 721 is 7 x 103
Prime Factorization of 62 is 2 x 31
Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2
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(658, 721) = 67774
GCD(658, 721) = ( 658 x 721 ) / 67774
GCD(658, 721) = 474418 / 67774
GCD(658, 721) = 7
Step2:
Here we consider the GCD from the above i.e. 7 as first number and the next as 62
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(7, 62) = 434
GCD(7, 62) = ( 7 x 62 ) / 434
GCD(7, 62) = 434 / 434
GCD(7, 62) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 128
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
GCD(1, 128) = 128 / 128
GCD(1, 128) = 1
GCD of 658, 721, 62, 128 is 1
