Given numbers are 778,150,915,846,942
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,150,915,846,942 is 78793330950.
Find LCM of 778,150,915,846,942 with Prime Factorization
| 2 | 778, 150, 915, 846, 942 |
| 3 | 389, 75, 915, 423, 471 |
| 5 | 389, 25, 305, 141, 157 |
| 389, 5, 61, 141, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 389 x 5 x 61 x 141 x 157 = 78793330950
Therefore, the lowest common multiple of 778,150,915,846,942 is 78793330950.
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.
778 x 150 x 915 x 846 x 942 = 85096797426000
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.
778 : 1, 2, 389, 778
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
915 : 1, 3, 5, 15, 61, 183, 305, 915
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,150,915,846,942, is 1.
Now, the common factors can be found like this.
778:2x 389
150:2x 3x 5x 5
915:3x 5x 61
846:2x 3x 3x 47
942:2x 3x 157
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 3x 3x 3x 5 = 1080
Therefore, the value for common factors is 1080.
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 = 85096797426000/(1x1080)
LCM = 85096797426000/1080
LCM = 78793330950
Thus, we can understand that the LCM of 778,150,915,846,942 is 78793330950.
