Find LCM of 783,864,862,180,491 with Prime Factorization
| 2 | 783, 864, 862, 180, 491 |
| 2 | 783, 432, 431, 90, 491 |
| 3 | 783, 216, 431, 45, 491 |
| 3 | 261, 72, 431, 15, 491 |
| 3 | 87, 24, 431, 5, 491 |
| 29, 8, 431, 5, 491 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 29 x 8 x 431 x 5 x 491 = 26511878880
Therefore, the lowest common multiple of 783,864,862,180,491 is 26511878880.
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.
783 x 864 x 862 x 180 x 491 = 51539092542720
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.
783 : 1, 3, 9, 27, 29, 87, 261, 783
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
862 : 1, 2, 431, 862
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
491 : 1, 491
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,864,862,180,491, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
864:2x 2x 2x 2x 2x 3x 3x 3
862:2x 431
180:2x 2x 3x 3x 5
491:491
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 3x 3 = 1944
Therefore, the value for common factors is 1944.
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 = 51539092542720/(1x1944)
LCM = 51539092542720/1944
LCM = 26511878880
Thus, we can understand that the LCM of 783,864,862,180,491 is 26511878880.
