Given numbers are 655,771,917,600
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,771,917,600 is 141401400.
Find LCM of 655,771,917,600 with Prime Factorization
| 3 | 655, 771, 917, 600 |
| 5 | 655, 257, 917, 200 |
| 131 | 131, 257, 917, 40 |
| 1, 257, 7, 40 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 131 x 1 x 257 x 7 x 40 = 141401400
Therefore, the lowest common multiple of 655,771,917,600 is 141401400.
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.
655 x 771 x 917 x 600 = 277853751000
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.
655 : 1, 5, 131, 655
771 : 1, 3, 257, 771
917 : 1, 7, 131, 917
600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,771,917,600, is 1.
Now, the common factors can be found like this.
655:5x 131
771:3x 257
917:7x 131
600:2x 2x 2x 3x 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.
3x 5x 131 = 1965
Therefore, the value for common factors is 1965.
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 = 277853751000/(1x1965)
LCM = 277853751000/1965
LCM = 141401400
Thus, we can understand that the LCM of 655,771,917,600 is 141401400.
