Find LCM of 664,444,939,111,640 with Prime Factorization
| 2 | 664, 444, 939, 111, 640 |
| 2 | 332, 222, 939, 111, 320 |
| 2 | 166, 111, 939, 111, 160 |
| 3 | 83, 111, 939, 111, 80 |
| 37 | 83, 37, 313, 37, 80 |
| 83, 1, 313, 1, 80 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 37 x 83 x 1 x 313 x 1 x 80 = 1845548160
Therefore, the lowest common multiple of 664,444,939,111,640 is 1845548160.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
664 x 444 x 939 x 111 x 640 = 19666161192960
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
664 : 1, 2, 4, 8, 83, 166, 332, 664
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
939 : 1, 3, 313, 939
111 : 1, 3, 37, 111
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,444,939,111,640, is 1.
Now, the common factors can be found like this.
664:2x 2x 2x 83
444:2x 2x 3x 37
939:3x 313
111:3x 37
640:2x 2x 2x 2x 2x 2x 2x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 3x 3x 37 = 10656
Therefore, the value for common factors is 10656.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 19666161192960/(1x10656)
LCM = 19666161192960/10656
LCM = 1845548160
Thus, we can understand that the LCM of 664,444,939,111,640 is 1845548160.
