Given numbers are 483,969,257,918
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 483,969,257,918 is 721697634.
Find LCM of 483,969,257,918 with Prime Factorization
| 3 | 483, 969, 257, 918 |
| 17 | 161, 323, 257, 306 |
| 161, 19, 257, 18 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 161 x 19 x 257 x 18 = 721697634
Therefore, the lowest common multiple of 483,969,257,918 is 721697634.
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.
483 x 969 x 257 x 918 = 110419738002
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.
483 : 1, 3, 7, 21, 23, 69, 161, 483
969 : 1, 3, 17, 19, 51, 57, 323, 969
257 : 1, 257
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 483,969,257,918, is 1.
Now, the common factors can be found like this.
483:3x 7x 23
969:3x 17x 19
257:257
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.
3x 3x 17 = 153
Therefore, the value for common factors is 153.
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 = 110419738002/(1x153)
LCM = 110419738002/153
LCM = 721697634
Thus, we can understand that the LCM of 483,969,257,918 is 721697634.
