Answer:
2
Step-by-step explanation:
If we break 60 down using prime factorization, prime numbers in parentheses()
60 = (2) x 30
Wait a minute, if we look here, we will just do the prime factorization of 30 after this, just without a 2, so now we can conclude that the prime factorization of 30 is just missing the prime number (2) to become 60.
Just for fun let us break down 30 and 60 even further:
60:
60 = (2) x 30
30 = (2) x 15
15 = (3) x (5)
The prime factorization of 60 is 2 x 2 x 3 x 5, or 2^2 x 3 x 5. Don't forget when listing prime numbers we put them in order lest to greatest.
30:
30 = (2) x 15
15 = (3) x (5)
The prime factorization of 30 is 2 x 3 x 5.
