Find LCM of 657,844,920,455,273 with Prime Factorization
| 2 | 657, 844, 920, 455, 273 |
| 2 | 657, 422, 460, 455, 273 |
| 3 | 657, 211, 230, 455, 273 |
| 5 | 219, 211, 230, 455, 91 |
| 7 | 219, 211, 46, 91, 91 |
| 13 | 219, 211, 46, 13, 13 |
| 219, 211, 46, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 13 x 219 x 211 x 46 x 1 x 1 = 11605852440
Therefore, the lowest common multiple of 657,844,920,455,273 is 11605852440.
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.
657 x 844 x 920 x 455 x 273 = 63367954322400
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.
657 : 1, 3, 9, 73, 219, 657
844 : 1, 2, 4, 211, 422, 844
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
455 : 1, 5, 7, 13, 35, 65, 91, 455
273 : 1, 3, 7, 13, 21, 39, 91, 273
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,844,920,455,273, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
844:2x 2x 211
920:2x 2x 2x 5x 23
455:5x 7x 13
273:3x 7x 13
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 3x 5x 7x 13 = 5460
Therefore, the value for common factors is 5460.
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 = 63367954322400/(1x5460)
LCM = 63367954322400/5460
LCM = 11605852440
Thus, we can understand that the LCM of 657,844,920,455,273 is 11605852440.
