Given numbers are 917,518,705
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 917,518,705 is 47839890.
Find LCM of 917,518,705 with Prime Factorization
| 7 | 917, 518, 705 |
| 131, 74, 705 |
Multiply the prime numbers at the bottom and the left side.
7 x 131 x 74 x 705 = 47839890
Therefore, the lowest common multiple of 917,518,705 is 47839890.
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.
917 x 518 x 705 = 334879230
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.
917 : 1, 7, 131, 917
518 : 1, 2, 7, 14, 37, 74, 259, 518
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,518,705, is 1.
Now, the common factors can be found like this.
917:7x 131
518:2x 7x 37
705:3x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 334879230/(1x7)
LCM = 334879230/7
LCM = 47839890
Thus, we can understand that the LCM of 917,518,705 is 47839890.
