Find LCM of 918,153,398,299 with Prime Factorization
| 2 | 918, 153, 398, 299 |
| 3 | 459, 153, 199, 299 |
| 3 | 51, 153, 199, 299 |
| 17 | 17, 51, 199, 299 |
| 1, 3, 199, 299 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 1 x 3 x 199 x 299 = 54621918
Therefore, the lowest common multiple of 918,153,398,299 is 54621918.
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.
918 x 153 x 398 x 299 = 16714306908
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.
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
153 : 1, 3, 9, 17, 51, 153
398 : 1, 2, 199, 398
299 : 1, 13, 23, 299
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,153,398,299, is 1.
Now, the common factors can be found like this.
918:2x 3x 3x 3x 17
153:3x 3x 17
398:2x 199
299:13x 23
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 3x 17 = 306
Therefore, the value for common factors is 306.
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 = 16714306908/(1x306)
LCM = 16714306908/306
LCM = 54621918
Thus, we can understand that the LCM of 918,153,398,299 is 54621918.
