Find LCM of 608,858,252,905,780 with Prime Factorization
| 2 | 608, 858, 252, 905, 780 |
| 2 | 304, 429, 126, 905, 390 |
| 3 | 152, 429, 63, 905, 195 |
| 5 | 152, 143, 21, 905, 65 |
| 13 | 152, 143, 21, 181, 13 |
| 152, 11, 21, 181, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 152 x 11 x 21 x 181 x 1 = 4957112160
Therefore, the lowest common multiple of 608,858,252,905,780 is 4957112160.
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.
608 x 858 x 252 x 905 x 780 = 92797139635200
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.
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
905 : 1, 5, 181, 905
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 608,858,252,905,780, is 1.
Now, the common factors can be found like this.
608:2x 2x 2x 2x 2x 19
858:2x 3x 11x 13
252:2x 2x 3x 3x 7
905:5x 181
780:2x 2x 3x 5x 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 2x 2x 2x 2x 3x 3x 5x 13 = 18720
Therefore, the value for common factors is 18720.
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 = 92797139635200/(1x18720)
LCM = 92797139635200/18720
LCM = 4957112160
Thus, we can understand that the LCM of 608,858,252,905,780 is 4957112160.
