Find LCM of 668,208,635,455,841 with Prime Factorization
2 | 668, 208, 635, 455, 841 |
2 | 334, 104, 635, 455, 841 |
5 | 167, 52, 635, 455, 841 |
13 | 167, 52, 127, 91, 841 |
167, 4, 127, 7, 841 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 167 x 4 x 127 x 7 x 841 = 129851678320
Therefore, the lowest common multiple of 668,208,635,455,841 is 129851678320.
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.
668 x 208 x 635 x 455 x 841 = 33761436363200
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.
668 : 1, 2, 4, 167, 334, 668
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
635 : 1, 5, 127, 635
455 : 1, 5, 7, 13, 35, 65, 91, 455
841 : 1, 29, 841
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,208,635,455,841, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
208:2x 2x 2x 2x 13
635:5x 127
455:5x 7x 13
841:29x 29
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 13 = 260
Therefore, the value for common factors is 260.
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 = 33761436363200/(1x260)
LCM = 33761436363200/260
LCM = 129851678320
Thus, we can understand that the LCM of 668,208,635,455,841 is 129851678320.
