Given numbers are 919,742,290,906,400
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 919,742,290,906,400 is 1791618805200.
Find LCM of 919,742,290,906,400 with Prime Factorization
| 2 | 919, 742, 290, 906, 400 |
| 5 | 919, 371, 145, 453, 200 |
| 919, 371, 29, 453, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 919 x 371 x 29 x 453 x 40 = 1791618805200
Therefore, the lowest common multiple of 919,742,290,906,400 is 1791618805200.
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.
919 x 742 x 290 x 906 x 400 = 71664752208000
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.
919 : 1, 919
742 : 1, 2, 7, 14, 53, 106, 371, 742
290 : 1, 2, 5, 10, 29, 58, 145, 290
906 : 1, 2, 3, 6, 151, 302, 453, 906
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 919,742,290,906,400, is 1.
Now, the common factors can be found like this.
919:919
742:2x 7x 53
290:2x 5x 29
906:2x 3x 151
400:2x 2x 2x 2x 5x 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 2x 5 = 40
Therefore, the value for common factors is 40.
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 = 71664752208000/(1x40)
LCM = 71664752208000/40
LCM = 1791618805200
Thus, we can understand that the LCM of 919,742,290,906,400 is 1791618805200.
