Given numbers are 781,552,990,186,709
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,552,990,186,709 is 142131159720.
Find LCM of 781,552,990,186,709 with Prime Factorization
| 2 | 781, 552, 990, 186, 709 |
| 3 | 781, 276, 495, 93, 709 |
| 11 | 781, 92, 165, 31, 709 |
| 71, 92, 15, 31, 709 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 71 x 92 x 15 x 31 x 709 = 142131159720
Therefore, the lowest common multiple of 781,552,990,186,709 is 142131159720.
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.
781 x 552 x 990 x 186 x 709 = 56283939249120
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.
781 : 1, 11, 71, 781
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
186 : 1, 2, 3, 6, 31, 62, 93, 186
709 : 1, 709
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,552,990,186,709, is 1.
Now, the common factors can be found like this.
781:11x 71
552:2x 2x 2x 3x 23
990:2x 3x 3x 5x 11
186:2x 3x 31
709:709
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 11 = 396
Therefore, the value for common factors is 396.
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 = 56283939249120/(1x396)
LCM = 56283939249120/396
LCM = 142131159720
Thus, we can understand that the LCM of 781,552,990,186,709 is 142131159720.
