Given numbers are 838,132,616,803,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,132,616,803,905 is 51154922280.
Find LCM of 838,132,616,803,905 with Prime Factorization
| 2 | 838, 132, 616, 803, 905 |
| 2 | 419, 66, 308, 803, 905 |
| 11 | 419, 33, 154, 803, 905 |
| 419, 3, 14, 73, 905 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 419 x 3 x 14 x 73 x 905 = 51154922280
Therefore, the lowest common multiple of 838,132,616,803,905 is 51154922280.
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.
838 x 132 x 616 x 803 x 905 = 49517964767040
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.
838 : 1, 2, 419, 838
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
803 : 1, 11, 73, 803
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,132,616,803,905, is 1.
Now, the common factors can be found like this.
838:2x 419
132:2x 2x 3x 11
616:2x 2x 2x 7x 11
803:11x 73
905:5x 181
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 11x 11 = 968
Therefore, the value for common factors is 968.
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 = 49517964767040/(1x968)
LCM = 49517964767040/968
LCM = 51154922280
Thus, we can understand that the LCM of 838,132,616,803,905 is 51154922280.
