Find LCM of 418,639,855,847 with Prime Factorization
3 | 418, 639, 855, 847 |
3 | 418, 213, 285, 847 |
11 | 418, 71, 95, 847 |
19 | 38, 71, 95, 77 |
2, 71, 5, 77 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 19 x 2 x 71 x 5 x 77 = 102834270
Therefore, the lowest common multiple of 418,639,855,847 is 102834270.
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.
418 x 639 x 855 x 847 = 193431261870
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
639 : 1, 3, 9, 71, 213, 639
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,639,855,847, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
639:3x 3x 71
855:3x 3x 5x 19
847:7x 11x 11
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 11x 19 = 1881
Therefore, the value for common factors is 1881.
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 = 193431261870/(1x1881)
LCM = 193431261870/1881
LCM = 102834270
Thus, we can understand that the LCM of 418,639,855,847 is 102834270.
