Make use of GCD Calculator to determine the Greatest Common Divisor of 620, 769, 80, 402 i.e. 1 largest integer that divides all the numbers equally.
GCD of 620, 769, 80, 402 is 1
GCD(620, 769, 80, 402) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 620, 769, 80, 402 is 1
GCD(620, 769, 80, 402) = 1
Given Input numbers are 620, 769, 80, 402
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 620

1, 2, 4, 5, 8, 10, 16, 20, 40, 80
Divisors of 402
List of positive integer divisors of 402 that divides 402 without a remainder.
1, 2, 3, 6, 67, 134, 201, 402
Greatest Common Divisior
We found the divisors of 620, 769, 80, 402 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 620, 769, 80, 402 is 1.
Therefore, GCD of numbers 620, 769, 80, 402 is 1
Given Input Data is 620, 769, 80, 402
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 620 is 2 x 2 x 5 x 31
Prime Factorization of 769 is 769
Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5
Prime Factorization of 402 is 2 x 3 x 67
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(620, 769) = 476780
GCD(620, 769) = ( 620 x 769 ) / 476780
GCD(620, 769) = 476780 / 476780
GCD(620, 769) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 80
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 80) = 80
GCD(1, 80) = ( 1 x 80 ) / 80
GCD(1, 80) = 80 / 80
GCD(1, 80) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 402
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 402) = 402
GCD(1, 402) = ( 1 x 402 ) / 402
GCD(1, 402) = 402 / 402
GCD(1, 402) = 1
GCD of 620, 769, 80, 402 is 1
