Given numbers are 838,450,781,176
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,450,781,176 is 1178060400.
Find LCM of 838,450,781,176 with Prime Factorization
| 2 | 838, 450, 781, 176 |
| 11 | 419, 225, 781, 88 |
| 419, 225, 71, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 419 x 225 x 71 x 8 = 1178060400
Therefore, the lowest common multiple of 838,450,781,176 is 1178060400.
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 450 x 781 x 176 = 51834657600
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
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
781 : 1, 11, 71, 781
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,450,781,176, is 1.
Now, the common factors can be found like this.
838:2x 419
450:2x 3x 3x 5x 5
781:11x 71
176:2x 2x 2x 2x 11
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 11 = 44
Therefore, the value for common factors is 44.
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 = 51834657600/(1x44)
LCM = 51834657600/44
LCM = 1178060400
Thus, we can understand that the LCM of 838,450,781,176 is 1178060400.
