The LCM of 862,290,560,408,722 is 128866689840.
Find LCM of 862,290,560,408,722 with Prime Factorization
| 2 | 862, 290, 560, 408, 722 |
| 2 | 431, 145, 280, 204, 361 |
| 2 | 431, 145, 140, 102, 361 |
| 5 | 431, 145, 70, 51, 361 |
| 431, 29, 14, 51, 361 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 431 x 29 x 14 x 51 x 361 = 128866689840
Therefore, the lowest common multiple of 862,290,560,408,722 is 128866689840.
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.
862 x 290 x 560 x 408 x 722 = 41237340748800
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.
862 : 1, 2, 431, 862
290 : 1, 2, 5, 10, 29, 58, 145, 290
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
722 : 1, 2, 19, 38, 361, 722
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,290,560,408,722, is 2.
Now, the common factors can be found like this.
862:2x 431
290:2x 5x 29
560:2x 2x 2x 2x 5x 7
408:2x 2x 2x 3x 17
722:2x 19x 19
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 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 41237340748800/(2x160)
LCM = 41237340748800/320
LCM = 128866689840
Thus, we can understand that the LCM of 862,290,560,408,722 is 128866689840.
