Factor tree of 40: 40 20,2 10,2,2 5,2,2,2
Here is a factor tree of eight: 8 / \ 4 2 / \ 2 2
873 x 29Since both 3 and 29 are prime numbers, the factor tree is complete.
To find the factor tree for 193, you start by determining the prime factors of 193. Since 193 is a prime number itself, the factor tree for 193 would simply consist of the number 193 at the top, as it cannot be broken down further into smaller prime factors. Therefore, the factor tree for 193 would just be a single branch with 193 as the prime factor.
5x3x17
46 23,2
46 2,23 2 x 23 = 46
92 /\ 2 46 /\ 2 23
46 2, 23
The highest common factor of 46 and 138 is 46Factorization method:46 = 2×23138 = 2×3×23highest common factor = 2×23 = 46Alternative (modular) method:138 mod 46 = 0so 46 is the highest common factor.
