Given numbers are 182,420,468,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 182,420,468,645 is 704340.
Find LCM of 182,420,468,645 with Prime Factorization
| 2 | 182, 420, 468, 645 |
| 2 | 91, 210, 234, 645 |
| 3 | 91, 105, 117, 645 |
| 5 | 91, 35, 39, 215 |
| 7 | 91, 7, 39, 43 |
| 13 | 13, 1, 39, 43 |
| 1, 1, 3, 43 |
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 3 x 43 = 704340
Therefore, the lowest common multiple of 182,420,468,645 is 704340.
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.
182 x 420 x 468 x 645 = 23074178400
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.
182 : 1, 2, 7, 13, 14, 26, 91, 182
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 182,420,468,645, is 1.
Now, the common factors can be found like this.
182:2x 7x 13
420:2x 2x 3x 5x 7
468:2x 2x 3x 3x 13
645:3x 5x 43
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 3x 5x 7x 13 = 32760
Therefore, the value for common factors is 32760.
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 = 23074178400/(1x32760)
LCM = 23074178400/32760
LCM = 704340
Thus, we can understand that the LCM of 182,420,468,645 is 704340.
