Find LCM of 865,785,446,840,903 with Prime Factorization
| 2 | 865, 785, 446, 840, 903 |
| 3 | 865, 785, 223, 420, 903 |
| 5 | 865, 785, 223, 140, 301 |
| 7 | 173, 157, 223, 28, 301 |
| 173, 157, 223, 4, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 173 x 157 x 223 x 4 x 43 = 218775336360
Therefore, the lowest common multiple of 865,785,446,840,903 is 218775336360.
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.
865 x 785 x 446 x 840 x 903 = 229714103178000
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.
865 : 1, 5, 173, 865
785 : 1, 5, 157, 785
446 : 1, 2, 223, 446
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
903 : 1, 3, 7, 21, 43, 129, 301, 903
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,785,446,840,903, is 1.
Now, the common factors can be found like this.
865:5x 173
785:5x 157
446:2x 223
840:2x 2x 2x 3x 5x 7
903:3x 7x 43
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 5x 5x 7 = 1050
Therefore, the value for common factors is 1050.
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 = 229714103178000/(1x1050)
LCM = 229714103178000/1050
LCM = 218775336360
Thus, we can understand that the LCM of 865,785,446,840,903 is 218775336360.
