Find LCM of 858,145,572,740 with Prime Factorization
| 2 | 858, 145, 572, 740 |
| 2 | 429, 145, 286, 370 |
| 5 | 429, 145, 143, 185 |
| 11 | 429, 29, 143, 37 |
| 13 | 39, 29, 13, 37 |
| 3, 29, 1, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 13 x 3 x 29 x 1 x 37 = 9206340
Therefore, the lowest common multiple of 858,145,572,740 is 9206340.
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.
858 x 145 x 572 x 740 = 52660264800
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
145 : 1, 5, 29, 145
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,145,572,740, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
145:5x 29
572:2x 2x 11x 13
740:2x 2x 5x 37
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 5x 11x 13 = 5720
Therefore, the value for common factors is 5720.
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 = 52660264800/(1x5720)
LCM = 52660264800/5720
LCM = 9206340
Thus, we can understand that the LCM of 858,145,572,740 is 9206340.
