The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 244,490,851,854,920 is 101745560.
Find LCM of 244,490,851,854,920 with Prime Factorization
| 2 | 244, 490, 851, 854, 920 |
| 2 | 122, 245, 851, 427, 460 |
| 5 | 61, 245, 851, 427, 230 |
| 7 | 61, 49, 851, 427, 46 |
| 23 | 61, 7, 851, 61, 46 |
| 61 | 61, 7, 37, 61, 2 |
| 1, 7, 37, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 23 x 61 x 1 x 7 x 37 x 1 x 2 = 101745560
Therefore, the lowest common multiple of 244,490,851,854,920 is 101745560.
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.
244 x 490 x 851 x 854 x 920 = 79939451580800
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.
244 : 1, 2, 4, 61, 122, 244
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
851 : 1, 23, 37, 851
854 : 1, 2, 7, 14, 61, 122, 427, 854
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 244,490,851,854,920, is 1.
Now, the common factors can be found like this.
244:2x 2x 61
490:2x 5x 7x 7
851:23x 37
854:2x 7x 61
920:2x 2x 2x 5x 23
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 5x 7x 23x 61 = 785680
Therefore, the value for common factors is 785680.
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 = 79939451580800/(1x785680)
LCM = 79939451580800/785680
LCM = 101745560
Thus, we can understand that the LCM of 244,490,851,854,920 is 101745560.
