Given numbers are 915,745,315,768,995
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 915,745,315,768,995 is 145854455040.
Find LCM of 915,745,315,768,995 with Prime Factorization
| 3 | 915, 745, 315, 768, 995 |
| 5 | 305, 745, 105, 256, 995 |
| 61, 149, 21, 256, 199 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 61 x 149 x 21 x 256 x 199 = 145854455040
Therefore, the lowest common multiple of 915,745,315,768,995 is 145854455040.
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.
915 x 745 x 315 x 768 x 995 = 164086261920000
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.
915 : 1, 3, 5, 15, 61, 183, 305, 915
745 : 1, 5, 149, 745
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
995 : 1, 5, 199, 995
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,745,315,768,995, is 1.
Now, the common factors can be found like this.
915:3x 5x 61
745:5x 149
315:3x 3x 5x 7
768:2x 2x 2x 2x 2x 2x 2x 2x 3
995:5x 199
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 5x 5x 5 = 1125
Therefore, the value for common factors is 1125.
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 = 164086261920000/(1x1125)
LCM = 164086261920000/1125
LCM = 145854455040
Thus, we can understand that the LCM of 915,745,315,768,995 is 145854455040.
