26 x 3 x 7 = 1344
1344 = 2 x 2 x 2 x 2 x 2 x 2 x 3 x 7 = 26 x 3 x 7.
194 2 x 97 Since both 2 and 97 are prime numbers, the prime factorization tree is complete.
In actual fact, the prime factorization of 42 is not 21 x 2, as 21 is not a prime number. The complete prime factorization of 42 is 2 x 3 x 7.
Once your prime factorization is complete and you discover that there are no numbers in common, the GCF is one and the numbers are declared to be relatively prime.
When the bottom branch consists entirely of prime numbers.
As product of its prime factors: 3*3*5 = 45
1220 610,2 305,2,2 61,5,2,2
231 = 31*71*111
the prime facotrization of 154 is 12 times 3 times 5
No, 3x5x4 is not a prime factorization of 60. A prime factorization of 60 would consist of only prime numbers. The prime factorization of 60 is 2x2x3x5.
When all the factors are prime numbers, that's a prime factorization.
