GCD of 150, 493, 77, 780 is 1
GCD(150, 493, 77, 780) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 150, 493, 77, 780 is 1
GCD(150, 493, 77, 780) = 1
Given Input numbers are 150, 493, 77, 780
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
Greatest Common Divisior
We found the divisors of 150, 493, 77, 780 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 150, 493, 77, 780 is 1.
Therefore, GCD of numbers 150, 493, 77, 780 is 1
Given Input Data is 150, 493, 77, 780
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 150 is 2 x 3 x 5 x 5
Prime Factorization of 493 is 17 x 29
Prime Factorization of 77 is 7 x 11
Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13
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(150, 493) = 73950
GCD(150, 493) = ( 150 x 493 ) / 73950
GCD(150, 493) = 73950 / 73950
GCD(150, 493) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 77
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 77) = 77
GCD(1, 77) = ( 1 x 77 ) / 77
GCD(1, 77) = 77 / 77
GCD(1, 77) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 780
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
GCD(1, 780) = 780 / 780
GCD(1, 780) = 1
GCD of 150, 493, 77, 780 is 1
