Given numbers are 725,647,700,921,520
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 725,647,700,921,520 is 314509158600.
Find LCM of 725,647,700,921,520 with Prime Factorization
| 2 | 725, 647, 700, 921, 520 |
| 2 | 725, 647, 350, 921, 260 |
| 5 | 725, 647, 175, 921, 130 |
| 5 | 145, 647, 35, 921, 26 |
| 29, 647, 7, 921, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 5 x 29 x 647 x 7 x 921 x 26 = 314509158600
Therefore, the lowest common multiple of 725,647,700,921,520 is 314509158600.
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.
725 x 647 x 700 x 921 x 520 = 157254579300000
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.
725 : 1, 5, 25, 29, 145, 725
647 : 1, 647
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
921 : 1, 3, 307, 921
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 725,647,700,921,520, is 1.
Now, the common factors can be found like this.
725:5x 5x 29
647:647
700:2x 2x 5x 5x 7
921:3x 307
520:2x 2x 2x 5x 13
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 5x 5x 5 = 500
Therefore, the value for common factors is 500.
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 = 157254579300000/(1x500)
LCM = 157254579300000/500
LCM = 314509158600
Thus, we can understand that the LCM of 725,647,700,921,520 is 314509158600.
