Find the GCF of the numbers using an appropriate method.

240, 10,000, and 4500

Find the prime factorization of the number, and write it in exponent form.

670

Find the LCM for the given numbers by an appropriate method.

24, 54, and 27

• math -

240 = 2x2x2x3x5
10000 = 2x2x2x2x5x5x5x5x5
4500 = 2x2x3x3x5x5x5
HCF = 2x2x5 = 20
(2x2x5) is the longest string of multipliers that appears in all 3 numbers.

670 = 2x5x67

24=2x2x3x3
54 = 2x3x3x3
27 = 3x3x3

LCM = 2x2x3x3x3 = 108

(write down the longest string of factors you see.
Look at your other numbers and include any factors not already listed)
