Find LCM of 288,855,438,560 with Prime Factorization
2 | 288, 855, 438, 560 |
2 | 144, 855, 219, 280 |
2 | 72, 855, 219, 140 |
2 | 36, 855, 219, 70 |
3 | 18, 855, 219, 35 |
3 | 6, 285, 73, 35 |
5 | 2, 95, 73, 35 |
2, 19, 73, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 5 x 2 x 19 x 73 x 7 = 13980960
Therefore, the lowest common multiple of 288,855,438,560 is 13980960.
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.
288 x 855 x 438 x 560 = 60397747200
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.
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
438 : 1, 2, 3, 6, 73, 146, 219, 438
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 288,855,438,560, is 1.
Now, the common factors can be found like this.
288:2x 2x 2x 2x 2x 3x 3
855:3x 3x 5x 19
438:2x 3x 73
560:2x 2x 2x 2x 5x 7
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 3x 5 = 4320
Therefore, the value for common factors is 4320.
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 = 60397747200/(1x4320)
LCM = 60397747200/4320
LCM = 13980960
Thus, we can understand that the LCM of 288,855,438,560 is 13980960.
