The LCM of 273,140,520,858 is 120120.
Find LCM of 273,140,520,858 with Prime Factorization
| 2 | 273, 140, 520, 858 |
| 2 | 273, 70, 260, 429 |
| 3 | 273, 35, 130, 429 |
| 5 | 91, 35, 130, 143 |
| 7 | 91, 7, 26, 143 |
| 13 | 13, 1, 26, 143 |
| 1, 1, 2, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 13 x 1 x 1 x 2 x 11 = 120120
Therefore, the lowest common multiple of 273,140,520,858 is 120120.
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.
273 x 140 x 520 x 858 = 17052235200
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.
273 : 1, 3, 7, 13, 21, 39, 91, 273
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
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 273,140,520,858, is 1.
Now, the common factors can be found like this.
273:3x 7x 13
140:2x 2x 5x 7
520:2x 2x 2x 5x 13
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 2x 2x 3x 5x 7x 13x 13 = 141960
Therefore, the value for common factors is 141960.
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 = 17052235200/(1x141960)
LCM = 17052235200/141960
LCM = 120120
Thus, we can understand that the LCM of 273,140,520,858 is 120120.
