Find LCM of 788,689,803,453,858 with Prime Factorization
| 2 | 788, 689, 803, 453, 858 |
| 3 | 394, 689, 803, 453, 429 |
| 11 | 394, 689, 803, 151, 143 |
| 13 | 394, 689, 73, 151, 13 |
| 394, 53, 73, 151, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 394 x 53 x 73 x 151 x 1 = 197496401388
Therefore, the lowest common multiple of 788,689,803,453,858 is 197496401388.
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.
788 x 689 x 803 x 453 x 858 = 169451912390904
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.
788 : 1, 2, 4, 197, 394, 788
689 : 1, 13, 53, 689
803 : 1, 11, 73, 803
453 : 1, 3, 151, 453
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,689,803,453,858, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
689:13x 53
803:11x 73
453:3x 151
858:2x 3x 11x 13
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 11x 13 = 858
Therefore, the value for common factors is 858.
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 = 169451912390904/(1x858)
LCM = 169451912390904/858
LCM = 197496401388
Thus, we can understand that the LCM of 788,689,803,453,858 is 197496401388.
