Given numbers are 826,703,820,245,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 826,703,820,245,821 is 1368234151060.
Find LCM of 826,703,820,245,821 with Prime Factorization
| 2 | 826, 703, 820, 245, 821 |
| 5 | 413, 703, 410, 245, 821 |
| 7 | 413, 703, 82, 49, 821 |
| 59, 703, 82, 7, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 59 x 703 x 82 x 7 x 821 = 1368234151060
Therefore, the lowest common multiple of 826,703,820,245,821 is 1368234151060.
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.
826 x 703 x 820 x 245 x 821 = 95776390574200
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.
826 : 1, 2, 7, 14, 59, 118, 413, 826
703 : 1, 19, 37, 703
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
245 : 1, 5, 7, 35, 49, 245
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 826,703,820,245,821, is 1.
Now, the common factors can be found like this.
826:2x 7x 59
703:19x 37
820:2x 2x 5x 41
245:5x 7x 7
821:821
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7 = 70
Therefore, the value for common factors is 70.
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 = 95776390574200/(1x70)
LCM = 95776390574200/70
LCM = 1368234151060
Thus, we can understand that the LCM of 826,703,820,245,821 is 1368234151060.
