Given numbers are 512,447,708,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 512,447,708,780 is 877693440.
Find LCM of 512,447,708,780 with Prime Factorization
| 2 | 512, 447, 708, 780 |
| 2 | 256, 447, 354, 390 |
| 3 | 128, 447, 177, 195 |
| 128, 149, 59, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 128 x 149 x 59 x 65 = 877693440
Therefore, the lowest common multiple of 512,447,708,780 is 877693440.
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.
512 x 447 x 708 x 780 = 126387855360
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.
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
447 : 1, 3, 149, 447
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 512,447,708,780, is 1.
Now, the common factors can be found like this.
512:2x 2x 2x 2x 2x 2x 2x 2x 2
447:3x 149
708:2x 2x 3x 59
780:2x 2x 3x 5x 13
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 126387855360/(1x144)
LCM = 126387855360/144
LCM = 877693440
Thus, we can understand that the LCM of 512,447,708,780 is 877693440.
