Given numbers are 579,299,280,210,647
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 579,299,280,210,647 is 31362600360.
Find LCM of 579,299,280,210,647 with Prime Factorization
| 2 | 579, 299, 280, 210, 647 |
| 3 | 579, 299, 140, 105, 647 |
| 5 | 193, 299, 140, 35, 647 |
| 7 | 193, 299, 28, 7, 647 |
| 193, 299, 4, 1, 647 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 193 x 299 x 4 x 1 x 647 = 31362600360
Therefore, the lowest common multiple of 579,299,280,210,647 is 31362600360.
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.
579 x 299 x 280 x 210 x 647 = 6586146075600
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.
579 : 1, 3, 193, 579
299 : 1, 13, 23, 299
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
647 : 1, 647
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 579,299,280,210,647, is 1.
Now, the common factors can be found like this.
579:3x 193
299:13x 23
280:2x 2x 2x 5x 7
210:2x 3x 5x 7
647:647
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 6586146075600/(1x210)
LCM = 6586146075600/210
LCM = 31362600360
Thus, we can understand that the LCM of 579,299,280,210,647 is 31362600360.
