Given numbers are 994,639,516,240
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 994,639,516,240 is 15387120.
Find LCM of 994,639,516,240 with Prime Factorization
| 2 | 994, 639, 516, 240 |
| 2 | 497, 639, 258, 120 |
| 3 | 497, 639, 129, 60 |
| 71 | 497, 213, 43, 20 |
| 7, 3, 43, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 71 x 7 x 3 x 43 x 20 = 15387120
Therefore, the lowest common multiple of 994,639,516,240 is 15387120.
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 639 x 516 x 240 = 78658957440
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
639 : 1, 3, 9, 71, 213, 639
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 994,639,516,240, is 1.
Now, the common factors can be found like this.
994:2x 7x 71
639:3x 3x 71
516:2x 2x 3x 43
240:2x 2x 2x 2x 3x 5
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 3x 71 = 5112
Therefore, the value for common factors is 5112.
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 = 78658957440/(1x5112)
LCM = 78658957440/5112
LCM = 15387120
Thus, we can understand that the LCM of 994,639,516,240 is 15387120.
