Find LCM of 378,630,919,864,225 with Prime Factorization
| 2 | 378, 630, 919, 864, 225 |
| 3 | 189, 315, 919, 432, 225 |
| 3 | 63, 105, 919, 144, 75 |
| 3 | 21, 35, 919, 48, 25 |
| 5 | 7, 35, 919, 16, 25 |
| 7 | 7, 7, 919, 16, 5 |
| 1, 1, 919, 16, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 7 x 1 x 1 x 919 x 16 x 5 = 138952800
Therefore, the lowest common multiple of 378,630,919,864,225 is 138952800.
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.
378 x 630 x 919 x 864 x 225 = 42544568304000
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
919 : 1, 919
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,630,919,864,225, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
630:2x 3x 3x 5x 7
919:919
864:2x 2x 2x 2x 2x 3x 3x 3
225:3x 3x 5x 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 3x 3x 3x 3x 3x 3x 3x 5x 7 = 306180
Therefore, the value for common factors is 306180.
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 = 42544568304000/(1x306180)
LCM = 42544568304000/306180
LCM = 138952800
Thus, we can understand that the LCM of 378,630,919,864,225 is 138952800.
