Given numbers are 296,781,390,985
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 296,781,390,985 is 8880626040.
Find LCM of 296,781,390,985 with Prime Factorization
| 2 | 296, 781, 390, 985 |
| 5 | 148, 781, 195, 985 |
| 148, 781, 39, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 148 x 781 x 39 x 197 = 8880626040
Therefore, the lowest common multiple of 296,781,390,985 is 8880626040.
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.
296 x 781 x 390 x 985 = 88806260400
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.
296 : 1, 2, 4, 8, 37, 74, 148, 296
781 : 1, 11, 71, 781
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
985 : 1, 5, 197, 985
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 296,781,390,985, is 1.
Now, the common factors can be found like this.
296:2x 2x 2x 37
781:11x 71
390:2x 3x 5x 13
985:5x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 88806260400/(1x10)
LCM = 88806260400/10
LCM = 8880626040
Thus, we can understand that the LCM of 296,781,390,985 is 8880626040.
