Find LCM of 858,545,581,158,975 with Prime Factorization
| 2 | 858, 545, 581, 158, 975 |
| 3 | 429, 545, 581, 79, 975 |
| 5 | 143, 545, 581, 79, 325 |
| 13 | 143, 109, 581, 79, 65 |
| 11, 109, 581, 79, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 11 x 109 x 581 x 79 x 5 = 107314156950
Therefore, the lowest common multiple of 858,545,581,158,975 is 107314156950.
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 545 x 581 x 158 x 975 = 41852521210500
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
545 : 1, 5, 109, 545
581 : 1, 7, 83, 581
158 : 1, 2, 79, 158
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,545,581,158,975, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
545:5x 109
581:7x 83
158:2x 79
975:3x 5x 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 3x 5x 13 = 390
Therefore, the value for common factors is 390.
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 = 41852521210500/(1x390)
LCM = 41852521210500/390
LCM = 107314156950
Thus, we can understand that the LCM of 858,545,581,158,975 is 107314156950.
