The LCM of 906,805,297,637,221 is 111699077490.
Find LCM of 906,805,297,637,221 with Prime Factorization
| 3 | 906, 805, 297, 637, 221 |
| 7 | 302, 805, 99, 637, 221 |
| 13 | 302, 115, 99, 91, 221 |
| 302, 115, 99, 7, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 13 x 302 x 115 x 99 x 7 x 17 = 111699077490
Therefore, the lowest common multiple of 906,805,297,637,221 is 111699077490.
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.
906 x 805 x 297 x 637 x 221 = 30493848154770
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.
906 : 1, 2, 3, 6, 151, 302, 453, 906
805 : 1, 5, 7, 23, 35, 115, 161, 805
297 : 1, 3, 9, 11, 27, 33, 99, 297
637 : 1, 7, 13, 49, 91, 637
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,805,297,637,221, is 1.
Now, the common factors can be found like this.
906:2x 3x 151
805:5x 7x 23
297:3x 3x 3x 11
637:7x 7x 13
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 13 = 273
Therefore, the value for common factors is 273.
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 = 30493848154770/(1x273)
LCM = 30493848154770/273
LCM = 111699077490
Thus, we can understand that the LCM of 906,805,297,637,221 is 111699077490.
