Given numbers are 636,600,298,865
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 636,600,298,865 is 819708600.
Find LCM of 636,600,298,865 with Prime Factorization
| 2 | 636, 600, 298, 865 |
| 2 | 318, 300, 149, 865 |
| 3 | 159, 150, 149, 865 |
| 5 | 53, 50, 149, 865 |
| 53, 10, 149, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 53 x 10 x 149 x 173 = 819708600
Therefore, the lowest common multiple of 636,600,298,865 is 819708600.
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.
636 x 600 x 298 x 865 = 98365032000
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.
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
298 : 1, 2, 149, 298
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,600,298,865, is 1.
Now, the common factors can be found like this.
636:2x 2x 3x 53
600:2x 2x 2x 3x 5x 5
298:2x 149
865:5x 173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 98365032000/(1x120)
LCM = 98365032000/120
LCM = 819708600
Thus, we can understand that the LCM of 636,600,298,865 is 819708600.
