Find LCM of 895,644,768,944,421 with Prime Factorization
| 2 | 895, 644, 768, 944, 421 |
| 2 | 895, 322, 384, 472, 421 |
| 2 | 895, 161, 192, 236, 421 |
| 2 | 895, 161, 96, 118, 421 |
| 895, 161, 48, 59, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 895 x 161 x 48 x 59 x 421 = 2748806941440
Therefore, the lowest common multiple of 895,644,768,944,421 is 2748806941440.
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.
895 x 644 x 768 x 944 x 421 = 175923644252160
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.
895 : 1, 5, 179, 895
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 895,644,768,944,421, is 1.
Now, the common factors can be found like this.
895:5x 179
644:2x 2x 7x 23
768:2x 2x 2x 2x 2x 2x 2x 2x 3
944:2x 2x 2x 2x 59
421:421
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 2 = 64
Therefore, the value for common factors is 64.
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 = 175923644252160/(1x64)
LCM = 175923644252160/64
LCM = 2748806941440
Thus, we can understand that the LCM of 895,644,768,944,421 is 2748806941440.
