The LCM of 994,687,400,375,390 is 8877414000.
Find LCM of 994,687,400,375,390 with Prime Factorization
| 2 | 994, 687, 400, 375, 390 |
| 3 | 497, 687, 200, 375, 195 |
| 5 | 497, 229, 200, 125, 65 |
| 5 | 497, 229, 40, 25, 13 |
| 497, 229, 8, 5, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 5 x 497 x 229 x 8 x 5 x 13 = 8877414000
Therefore, the lowest common multiple of 994,687,400,375,390 is 8877414000.
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.
994 x 687 x 400 x 375 x 390 = 39948363000000
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.
994 : 1, 2, 7, 14, 71, 142, 497, 994
687 : 1, 3, 229, 687
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
375 : 1, 3, 5, 15, 25, 75, 125, 375
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 994,687,400,375,390, is 1.
Now, the common factors can be found like this.
994:2x 7x 71
687:3x 229
400:2x 2x 2x 2x 5x 5
375:3x 5x 5x 5
390:2x 3x 5x 13
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 3x 3x 5x 5x 5 = 4500
Therefore, the value for common factors is 4500.
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 = 39948363000000/(1x4500)
LCM = 39948363000000/4500
LCM = 8877414000
Thus, we can understand that the LCM of 994,687,400,375,390 is 8877414000.
