Make use of GCD Calculator to determine the Greatest Common Divisor of 770, 805, 70, 356 i.e. 1 largest integer that divides all the numbers equally.
GCD of 770, 805, 70, 356 is 1
GCD(770, 805, 70, 356) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 770, 805, 70, 356 is 1
GCD(770, 805, 70, 356) = 1
Given Input numbers are 770, 805, 70, 356
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 770

1, 2, 4, 89, 178, 356
Greatest Common Divisior
We found the divisors of 770, 805, 70, 356 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 770, 805, 70, 356 is 1.
Therefore, GCD of numbers 770, 805, 70, 356 is 1
Given Input Data is 770, 805, 70, 356
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 770 is 2 x 5 x 7 x 11
Prime Factorization of 805 is 5 x 7 x 23
Prime Factorization of 70 is 2 x 5 x 7
Prime Factorization of 356 is 2 x 2 x 89
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(770, 805) = 17710
GCD(770, 805) = ( 770 x 805 ) / 17710
GCD(770, 805) = 619850 / 17710
GCD(770, 805) = 35
Step2:
Here we consider the GCD from the above i.e. 35 as first number and the next as 70
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(35, 70) = 70
GCD(35, 70) = ( 35 x 70 ) / 70
GCD(35, 70) = 2450 / 70
GCD(35, 70) = 35
Step3:
Here we consider the GCD from the above i.e. 35 as first number and the next as 356
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(35, 356) = 12460
GCD(35, 356) = ( 35 x 356 ) / 12460
GCD(35, 356) = 12460 / 12460
GCD(35, 356) = 1
GCD of 770, 805, 70, 356 is 1
