Given numbers are 153,822,456,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 153,822,456,391 is 73279656.
Find LCM of 153,822,456,391 with Prime Factorization
| 2 | 153, 822, 456, 391 |
| 3 | 153, 411, 228, 391 |
| 17 | 51, 137, 76, 391 |
| 3, 137, 76, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 3 x 137 x 76 x 23 = 73279656
Therefore, the lowest common multiple of 153,822,456,391 is 73279656.
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.
153 x 822 x 456 x 391 = 22423574736
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.
153 : 1, 3, 9, 17, 51, 153
822 : 1, 2, 3, 6, 137, 274, 411, 822
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,822,456,391, is 1.
Now, the common factors can be found like this.
153:3x 3x 17
822:2x 3x 137
456:2x 2x 2x 3x 19
391:17x 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 = 22423574736/(1x306)
LCM = 22423574736/306
LCM = 73279656
Thus, we can understand that the LCM of 153,822,456,391 is 73279656.
