Given numbers are 709,470,987,518
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 709,470,987,518 is 258919710.
Find LCM of 709,470,987,518 with Prime Factorization
| 2 | 709, 470, 987, 518 |
| 7 | 709, 235, 987, 259 |
| 47 | 709, 235, 141, 37 |
| 709, 5, 3, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 47 x 709 x 5 x 3 x 37 = 258919710
Therefore, the lowest common multiple of 709,470,987,518 is 258919710.
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.
709 x 470 x 987 x 518 = 170369169180
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.
709 : 1, 709
470 : 1, 2, 5, 10, 47, 94, 235, 470
987 : 1, 3, 7, 21, 47, 141, 329, 987
518 : 1, 2, 7, 14, 37, 74, 259, 518
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 709,470,987,518, is 1.
Now, the common factors can be found like this.
709:709
470:2x 5x 47
987:3x 7x 47
518:2x 7x 37
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 47 = 658
Therefore, the value for common factors is 658.
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 = 170369169180/(1x658)
LCM = 170369169180/658
LCM = 258919710
Thus, we can understand that the LCM of 709,470,987,518 is 258919710.
