The LCM of 845,572,820,275 is 7621900.
Find LCM of 845,572,820,275 with Prime Factorization
| 2 | 845, 572, 820, 275 |
| 2 | 845, 286, 410, 275 |
| 5 | 845, 143, 205, 275 |
| 11 | 169, 143, 41, 55 |
| 13 | 169, 13, 41, 5 |
| 1, 13, 41, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 13 x 1 x 13 x 41 x 5 = 7621900
Therefore, the lowest common multiple of 845,572,820,275 is 7621900.
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.
845 x 572 x 820 x 275 = 108993170000
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.
845 : 1, 5, 13, 65, 169, 845
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
275 : 1, 5, 11, 25, 55, 275
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,572,820,275, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
572:2x 2x 11x 13
820:2x 2x 5x 41
275:5x 5x 11
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 11x 13 = 14300
Therefore, the value for common factors is 14300.
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 = 108993170000/(1x14300)
LCM = 108993170000/14300
LCM = 7621900
Thus, we can understand that the LCM of 845,572,820,275 is 7621900.
