See the entire solution process below: To find the GCF (Greatest Common Factor) we need to factor each number separately and then find the all the common factors: 40 = 2 xx 2 xx 2 xx 5 100 = 2 xx 2 xx 5 xx 5 The common factors are: 40 = color(red)(2 xx 2) xx 2 xx color(red)(5) 100 = color(red)(2 xx 2) xx color(red)(5) xx 5 Or color(red)(2 xx 2 xx 5) = 20 The GCF is 20

The general rule is to decompose the numbers into prime factors and then the lcm in the product of all factors raised to the highest power found in those numbers. #8=2^3# #10=2xx5# #12=2^2xx3# #lcm(8,10,12)= 2^3xx3xx5=120#

Jan 8, 2017 · The GCF of 24 and 40 is 8 Given two positive numbers, one method for finding their GCF goes as follows: If the numbers are the same, then that is the GCF. Otherwise, replace the larger number by the result of subtracting the smaller number from it and repeat. So in our example: Start with 24, 40 Subtract 24 from 40 to get: 24, 16 Subtract 16 from 24 to get: 8, 16 Subtract 8 from 16 to get: 8 ...

Apr 9, 2018 · Next, we look to find a pair of numbers that when multiplied will give 25 and when added will give -40. The x^2 term has a non-one coefficient, so this will affect possible pairs. The factors of 25 are: (1, 25) (5,5) The factors of 16 are: (1,16) (4,4) We need to select one pair from the top list and one pair from the bottom list.

May 2, 2018 · First, notice all terms have #m#, so that can be factored out: #6m^3-18m^2-240m# #=m(6m^2-18m-240)# #6#, #18#, and #240# These numbers' GCF is #6#, so we can factor that out aswell: #=6m(m^2-3m-40)# Now we can factor the parentheses: #m^2-3m-40# Factors of 40: #1,40# #2,20# #4,10# #5,8# #5# and #8# can be subtracted to get #-3#, so these are ...

Feb 12, 2017 · All factors of 22 are: 1, 2, 11, 22 To find all factors of a certain number, you have to find all the numbers that it is divisible by. In this case the number is 22. Every number is divisible by 1 and by itself, so two of the factors are: 1 and 22 Then continue to divide 22 by all numbers less than 22, or until two factors meet. 22 is an even number, therefore it is divisible by 2, so another ...
