Find LCM of 817,906,567,357,221 with Prime Factorization
| 3 | 817, 906, 567, 357, 221 |
| 7 | 817, 302, 189, 119, 221 |
| 17 | 817, 302, 27, 17, 221 |
| 817, 302, 27, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 17 x 817 x 302 x 27 x 1 x 13 = 30917497338
Therefore, the lowest common multiple of 817,906,567,357,221 is 30917497338.
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.
817 x 906 x 567 x 357 x 221 = 33112639648998
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.
817 : 1, 19, 43, 817
906 : 1, 2, 3, 6, 151, 302, 453, 906
567 : 1, 3, 7, 9, 21, 27, 63, 81, 189, 567
357 : 1, 3, 7, 17, 21, 51, 119, 357
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,906,567,357,221, is 1.
Now, the common factors can be found like this.
817:19x 43
906:2x 3x 151
567:3x 3x 3x 3x 7
357:3x 7x 17
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 3x 7x 17 = 1071
Therefore, the value for common factors is 1071.
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 = 33112639648998/(1x1071)
LCM = 33112639648998/1071
LCM = 30917497338
Thus, we can understand that the LCM of 817,906,567,357,221 is 30917497338.
