Find LCM of 845,105,759,690,908 with Prime Factorization
2 | 845, 105, 759, 690, 908 |
3 | 845, 105, 759, 345, 454 |
5 | 845, 35, 253, 115, 454 |
23 | 169, 7, 253, 23, 454 |
169, 7, 11, 1, 454 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 169 x 7 x 11 x 1 x 454 = 4076452380
Therefore, the lowest common multiple of 845,105,759,690,908 is 4076452380.
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 105 x 759 x 690 x 908 = 42191282133000
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
105 : 1, 3, 5, 7, 15, 21, 35, 105
759 : 1, 3, 11, 23, 33, 69, 253, 759
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
908 : 1, 2, 4, 227, 454, 908
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,105,759,690,908, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
105:3x 5x 7
759:3x 11x 23
690:2x 3x 5x 23
908:2x 2x 227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 5x 23 = 10350
Therefore, the value for common factors is 10350.
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 = 42191282133000/(1x10350)
LCM = 42191282133000/10350
LCM = 4076452380
Thus, we can understand that the LCM of 845,105,759,690,908 is 4076452380.
