Given numbers are 515,721,826,282
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,721,826,282 is 59979990.
Find LCM of 515,721,826,282 with Prime Factorization
| 2 | 515, 721, 826, 282 |
| 7 | 515, 721, 413, 141 |
| 103 | 515, 103, 59, 141 |
| 5, 1, 59, 141 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 103 x 5 x 1 x 59 x 141 = 59979990
Therefore, the lowest common multiple of 515,721,826,282 is 59979990.
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.
515 x 721 x 826 x 282 = 86491145580
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.
515 : 1, 5, 103, 515
721 : 1, 7, 103, 721
826 : 1, 2, 7, 14, 59, 118, 413, 826
282 : 1, 2, 3, 6, 47, 94, 141, 282
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,721,826,282, is 1.
Now, the common factors can be found like this.
515:5x 103
721:7x 103
826:2x 7x 59
282:2x 3x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 103 = 1442
Therefore, the value for common factors is 1442.
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 = 86491145580/(1x1442)
LCM = 86491145580/1442
LCM = 59979990
Thus, we can understand that the LCM of 515,721,826,282 is 59979990.
