Given numbers are 910,687,475,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 910,687,475,138 is 1365996450.
Find LCM of 910,687,475,138 with Prime Factorization
| 2 | 910, 687, 475, 138 |
| 3 | 455, 687, 475, 69 |
| 5 | 455, 229, 475, 23 |
| 91, 229, 95, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 91 x 229 x 95 x 23 = 1365996450
Therefore, the lowest common multiple of 910,687,475,138 is 1365996450.
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.
910 x 687 x 475 x 138 = 40979893500
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.
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
687 : 1, 3, 229, 687
475 : 1, 5, 19, 25, 95, 475
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 910,687,475,138, is 1.
Now, the common factors can be found like this.
910:2x 5x 7x 13
687:3x 229
475:5x 5x 19
138:2x 3x 23
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 5 = 30
Therefore, the value for common factors is 30.
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 = 40979893500/(1x30)
LCM = 40979893500/30
LCM = 1365996450
Thus, we can understand that the LCM of 910,687,475,138 is 1365996450.
