First, factor each number and express this way:12 = 22 x 322 = 2 x 1130 = 2 x 3 x 5Now, take the greatest power of each factor and find the product: 22 x 3 x 5 x 11= 660 is the LCMNote: I selected only the 22 because it was the greatest power of 2 than any other factor of "2" in the other numbers. I selected one 3 beause it was the greatest power of 3, and one 5 and one 11 because they were unique factors. This method will effectively find the LCM of any set of numbers.
The common factors of 660 and 770 are: 1, 2, 5, 10, 11, 22, 55, and 110
Take the top two first.LCM is the product divided by the GCF55 factors to [5 11]60 factors to [2 2 3 5]common factor is 5, so LCM is 55 * 60 / 5 = 660Now, since 22 factors to [2 11] and both of them are in the above factors, 22 is a factor of 660 as well (22*30), so 660 is the answer. ■
6, 12, 18, 24, 30, 36, 60, 66, 72, 90, 120, 132, 180, 198, 264, 330, 360, 396, 660, 792, 990, 1320, 1980, 3960
The least common multiple of 15 , 44 = 660
Since 220 is a factor of 660, it is automatically the GCF.
The Greatest Common Factor (GCF) is: 60
The greatest common factor of 315 and 660 is 15.
The GCF is: 165
The GCF is: 3
The GCF is 11.
16.5*2=33
You need 2 or more numbers to perform GCF
lowest common factor of 20 and 33 is 660 mislead you there, dont think there is any greatest common factor because one number is odd and one even
The least common multiple is the product of the two numbers divided by their greatest common factor. The greatest common factor of 44 and 60 is 4, so the least common multiple is 44 x 60 ÷ 4 = 660.
The GCF is 44.
It is: 165
