Given numbers are 572,248,686,434
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 572,248,686,434 is 12164152.
Find LCM of 572,248,686,434 with Prime Factorization
| 2 | 572, 248, 686, 434 |
| 2 | 286, 124, 343, 217 |
| 7 | 143, 62, 343, 217 |
| 31 | 143, 62, 49, 31 |
| 143, 2, 49, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 31 x 143 x 2 x 49 x 1 = 12164152
Therefore, the lowest common multiple of 572,248,686,434 is 12164152.
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.
572 x 248 x 686 x 434 = 42233935744
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.
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
248 : 1, 2, 4, 8, 31, 62, 124, 248
686 : 1, 2, 7, 14, 49, 98, 343, 686
434 : 1, 2, 7, 14, 31, 62, 217, 434
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 572,248,686,434, is 2.
Now, the common factors can be found like this.
572:2x 2x 11x 13
248:2x 2x 2x 31
686:2x 7x 7x 7
434:2x 7x 31
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 7x 31 = 1736
Therefore, the value for common factors is 1736.
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 = 42233935744/(2x1736)
LCM = 42233935744/3472
LCM = 12164152
Thus, we can understand that the LCM of 572,248,686,434 is 12164152.
