Given numbers are 829,316,781,845,120
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 829,316,781,845,120 is 1037290991880.
Find LCM of 829,316,781,845,120 with Prime Factorization
| 2 | 829, 316, 781, 845, 120 |
| 2 | 829, 158, 781, 845, 60 |
| 5 | 829, 79, 781, 845, 30 |
| 829, 79, 781, 169, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 829 x 79 x 781 x 169 x 6 = 1037290991880
Therefore, the lowest common multiple of 829,316,781,845,120 is 1037290991880.
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.
829 x 316 x 781 x 845 x 120 = 20745819837600
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.
829 : 1, 829
316 : 1, 2, 4, 79, 158, 316
781 : 1, 11, 71, 781
845 : 1, 5, 13, 65, 169, 845
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 829,316,781,845,120, is 1.
Now, the common factors can be found like this.
829:829
316:2x 2x 79
781:11x 71
845:5x 13x 13
120:2x 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 5 = 20
Therefore, the value for common factors is 20.
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 = 20745819837600/(1x20)
LCM = 20745819837600/20
LCM = 1037290991880
Thus, we can understand that the LCM of 829,316,781,845,120 is 1037290991880.
