Given numbers are 338,442,572,430
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 338,442,572,430 is 27178580.
Find LCM of 338,442,572,430 with Prime Factorization
| 2 | 338, 442, 572, 430 |
| 13 | 169, 221, 286, 215 |
| 13, 17, 22, 215 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 13 x 17 x 22 x 215 = 27178580
Therefore, the lowest common multiple of 338,442,572,430 is 27178580.
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.
338 x 442 x 572 x 430 = 36745440160
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.
338 : 1, 2, 13, 26, 169, 338
442 : 1, 2, 13, 17, 26, 34, 221, 442
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
430 : 1, 2, 5, 10, 43, 86, 215, 430
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,442,572,430, is 2.
Now, the common factors can be found like this.
338:2x 13x 13
442:2x 13x 17
572:2x 2x 11x 13
430:2x 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 13x 13 = 676
Therefore, the value for common factors is 676.
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 = 36745440160/(2x676)
LCM = 36745440160/1352
LCM = 27178580
Thus, we can understand that the LCM of 338,442,572,430 is 27178580.
