Find LCM of 778,856,458,858,396 with Prime Factorization
| 2 | 778, 856, 458, 858, 396 |
| 2 | 389, 428, 229, 429, 198 |
| 3 | 389, 214, 229, 429, 99 |
| 11 | 389, 214, 229, 143, 33 |
| 389, 214, 229, 13, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 389 x 214 x 229 x 13 x 3 = 98138043432
Therefore, the lowest common multiple of 778,856,458,858,396 is 98138043432.
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.
778 x 856 x 458 x 858 x 396 = 103633773864192
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.
778 : 1, 2, 389, 778
856 : 1, 2, 4, 8, 107, 214, 428, 856
458 : 1, 2, 229, 458
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,856,458,858,396, is 2.
Now, the common factors can be found like this.
778:2x 389
856:2x 2x 2x 107
458:2x 229
858:2x 3x 11x 13
396:2x 2x 3x 3x 11
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 3x 11 = 528
Therefore, the value for common factors is 528.
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 = 103633773864192/(2x528)
LCM = 103633773864192/1056
LCM = 98138043432
Thus, we can understand that the LCM of 778,856,458,858,396 is 98138043432.
