34 = 2x17 64 = 2x2x2x2x2x2 GCF = 2
The GCF of 18, 24 and 64 is 2. To find the GCF of three numbers you first need to break them down into their prime factors: 18=2x3x3 24=2x2x2x3 64=2x2x2x2x2x2 The next step is to identify the common prime factors. The only prime factor which all three numbers have is 2. Therefore the GCF of 18, 24 and 64 is 2.
18
2x2x2x2x2x2
64 = 2x2x2x2x2x2
== The answer is 64== 2x2x2x2x2x2. ==
64=2x2x2x2x2x2
That's the prime factorization of 64.
2x2x2x2x2x2 or 2 to the 6th power.
Taking away - literally, rubbing/scoring it out - the amount of x2's needed to get the 16. e.g: 2x2x2x2x2x2 = 64 2x2x2x2 = 16 64/16 = 2x2x2x2x2x2 = 4 Much easier to add the sixteens until you have 64 and think back how many times you had to add.
Two to the power of 6 or 2x2x2x2x2x2
The prime factorization of 64 is 2x2x2x2x2x2 or 26.
4 x 4x 4= 12 2x2x2x2x2x2= 12
2to the sixth power. it's a Mathematical concept.
