Given numbers are 243,842,441,440,578
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 243,842,441,440,578 is 637433624520.
Find LCM of 243,842,441,440,578 with Prime Factorization
| 2 | 243, 842, 441, 440, 578 |
| 3 | 243, 421, 441, 220, 289 |
| 3 | 81, 421, 147, 220, 289 |
| 27, 421, 49, 220, 289 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 27 x 421 x 49 x 220 x 289 = 637433624520
Therefore, the lowest common multiple of 243,842,441,440,578 is 637433624520.
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.
243 x 842 x 441 x 440 x 578 = 22947610482720
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.
243 : 1, 3, 9, 27, 81, 243
842 : 1, 2, 421, 842
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
578 : 1, 2, 17, 34, 289, 578
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,842,441,440,578, is 1.
Now, the common factors can be found like this.
243:3x 3x 3x 3x 3
842:2x 421
441:3x 3x 7x 7
440:2x 2x 2x 5x 11
578:2x 17x 17
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 3 = 36
Therefore, the value for common factors is 36.
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 = 22947610482720/(1x36)
LCM = 22947610482720/36
LCM = 637433624520
Thus, we can understand that the LCM of 243,842,441,440,578 is 637433624520.
