Given numbers are 787,300,920,617
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 787,300,920,617 is 6700990200.
Find LCM of 787,300,920,617 with Prime Factorization
| 2 | 787, 300, 920, 617 |
| 2 | 787, 150, 460, 617 |
| 5 | 787, 75, 230, 617 |
| 787, 15, 46, 617 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 787 x 15 x 46 x 617 = 6700990200
Therefore, the lowest common multiple of 787,300,920,617 is 6700990200.
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.
787 x 300 x 920 x 617 = 134019804000
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.
787 : 1, 787
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
617 : 1, 617
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,300,920,617, is 1.
Now, the common factors can be found like this.
787:787
300:2x 2x 3x 5x 5
920:2x 2x 2x 5x 23
617:617
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 = 134019804000/(1x20)
LCM = 134019804000/20
LCM = 6700990200
Thus, we can understand that the LCM of 787,300,920,617 is 6700990200.
