Find LCM of 984,448,667,989,720 with Prime Factorization
| 2 | 984, 448, 667, 989, 720 |
| 2 | 492, 224, 667, 989, 360 |
| 2 | 246, 112, 667, 989, 180 |
| 2 | 123, 56, 667, 989, 90 |
| 3 | 123, 28, 667, 989, 45 |
| 23 | 41, 28, 667, 989, 15 |
| 41, 28, 29, 43, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 23 x 41 x 28 x 29 x 43 x 15 = 23706567360
Therefore, the lowest common multiple of 984,448,667,989,720 is 23706567360.
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.
984 x 448 x 667 x 989 x 720 = 209376402923520
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.
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
667 : 1, 23, 29, 667
989 : 1, 23, 43, 989
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 984,448,667,989,720, is 1.
Now, the common factors can be found like this.
984:2x 2x 2x 3x 41
448:2x 2x 2x 2x 2x 2x 7
667:23x 29
989:23x 43
720:2x 2x 2x 2x 3x 3x 5
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 2x 2x 3x 23 = 8832
Therefore, the value for common factors is 8832.
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 = 209376402923520/(1x8832)
LCM = 209376402923520/8832
LCM = 23706567360
Thus, we can understand that the LCM of 984,448,667,989,720 is 23706567360.
