Given numbers are 434,299,287,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 434,299,287,242 is 643769126.
Find LCM of 434,299,287,242 with Prime Factorization
| 2 | 434, 299, 287, 242 |
| 7 | 217, 299, 287, 121 |
| 31, 299, 41, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 31 x 299 x 41 x 121 = 643769126
Therefore, the lowest common multiple of 434,299,287,242 is 643769126.
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.
434 x 299 x 287 x 242 = 9012767764
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.
434 : 1, 2, 7, 14, 31, 62, 217, 434
299 : 1, 13, 23, 299
287 : 1, 7, 41, 287
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 434,299,287,242, is 1.
Now, the common factors can be found like this.
434:2x 7x 31
299:13x 23
287:7x 41
242:2x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 9012767764/(1x14)
LCM = 9012767764/14
LCM = 643769126
Thus, we can understand that the LCM of 434,299,287,242 is 643769126.
