250 = 2 x 5 x 5 x 5
69 = 3 x 23

PF of 175 = 5 x 5 x 7 or 52 x 71
As a product of its prime factors: 2*2*2*2*2*2*2*2 = 256 or as 2^8 = 256
PF of 462 = 2 x 3 x 7 x 11
42=2x21 21=3x7 PF=2x3x7 The PF (Prime Factorization) of 42 is 2x3x7.(Sorry, I couldn't do a factor tree, there are always helpful to use when doing prime factorization, but since this is the computer, I could only do it like the following above.)
The atomic number for the element Protactinium (Pf) is 91.
The prime factors are: 5, 7, 11
The prime factorization of 156 is 2^2 x 3 x 13. This means that 156 can be expressed as the product of these prime numbers. To find the prime factorization, you would first divide 156 by the smallest prime number, 2, then continue dividing by prime numbers until you reach the prime factorization.
3 and 7
No. They have to give the PF Account number if they are deducting PF
