Find LCM of 444,322,623,140,816 with Prime Factorization
| 2 | 444, 322, 623, 140, 816 |
| 2 | 222, 161, 623, 70, 408 |
| 3 | 111, 161, 623, 35, 204 |
| 7 | 37, 161, 623, 35, 68 |
| 37, 23, 89, 5, 68 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 37 x 23 x 89 x 5 x 68 = 2163105840
Therefore, the lowest common multiple of 444,322,623,140,816 is 2163105840.
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.
444 x 322 x 623 x 140 x 816 = 10175249871360
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.
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
322 : 1, 2, 7, 14, 23, 46, 161, 322
623 : 1, 7, 89, 623
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 444,322,623,140,816, is 1.
Now, the common factors can be found like this.
444:2x 2x 3x 37
322:2x 7x 23
623:7x 89
140:2x 2x 5x 7
816:2x 2x 2x 2x 3x 17
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 7x 7 = 4704
Therefore, the value for common factors is 4704.
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 = 10175249871360/(1x4704)
LCM = 10175249871360/4704
LCM = 2163105840
Thus, we can understand that the LCM of 444,322,623,140,816 is 2163105840.
