Given numbers are 230,220,856,918
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 230,220,856,918 is 497023560.
Find LCM of 230,220,856,918 with Prime Factorization
| 2 | 230, 220, 856, 918 |
| 2 | 115, 110, 428, 459 |
| 5 | 115, 55, 214, 459 |
| 23, 11, 214, 459 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 11 x 214 x 459 = 497023560
Therefore, the lowest common multiple of 230,220,856,918 is 497023560.
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.
230 x 220 x 856 x 918 = 39761884800
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.
230 : 1, 2, 5, 10, 23, 46, 115, 230
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
856 : 1, 2, 4, 8, 107, 214, 428, 856
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 230,220,856,918, is 2.
Now, the common factors can be found like this.
230:2x 5x 23
220:2x 2x 5x 11
856:2x 2x 2x 107
918:2x 3x 3x 3x 17
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 5 = 40
Therefore, the value for common factors is 40.
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 = 39761884800/(2x40)
LCM = 39761884800/80
LCM = 497023560
Thus, we can understand that the LCM of 230,220,856,918 is 497023560.
