Given numbers are 787,399,684,879
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 787,399,684,879 is 1104069708.
Find LCM of 787,399,684,879 with Prime Factorization
| 3 | 787, 399, 684, 879 |
| 19 | 787, 133, 228, 293 |
| 787, 7, 12, 293 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 787 x 7 x 12 x 293 = 1104069708
Therefore, the lowest common multiple of 787,399,684,879 is 1104069708.
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.
787 x 399 x 684 x 879 = 188795920068
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.
787 : 1, 787
399 : 1, 3, 7, 19, 21, 57, 133, 399
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
879 : 1, 3, 293, 879
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,399,684,879, is 1.
Now, the common factors can be found like this.
787:787
399:3x 7x 19
684:2x 2x 3x 3x 19
879:3x 293
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 19 = 171
Therefore, the value for common factors is 171.
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 = 188795920068/(1x171)
LCM = 188795920068/171
LCM = 1104069708
Thus, we can understand that the LCM of 787,399,684,879 is 1104069708.
