Find LCM of 784,231,819,894,541 with Prime Factorization
| 2 | 784, 231, 819, 894, 541 |
| 3 | 392, 231, 819, 447, 541 |
| 7 | 392, 77, 273, 149, 541 |
| 56, 11, 39, 149, 541 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 56 x 11 x 39 x 149 x 541 = 81335125872
Therefore, the lowest common multiple of 784,231,819,894,541 is 81335125872.
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.
784 x 231 x 819 x 894 x 541 = 71737581019104
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
231 : 1, 3, 7, 11, 21, 33, 77, 231
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
894 : 1, 2, 3, 6, 149, 298, 447, 894
541 : 1, 541
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,231,819,894,541, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
231:3x 7x 11
819:3x 3x 7x 13
894:2x 3x 149
541:541
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7x 7 = 882
Therefore, the value for common factors is 882.
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 = 71737581019104/(1x882)
LCM = 71737581019104/882
LCM = 81335125872
Thus, we can understand that the LCM of 784,231,819,894,541 is 81335125872.
