Given numbers are 946,418,780,661,807
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 946,418,780,661,807 is 1246416196740.
Find LCM of 946,418,780,661,807 with Prime Factorization
| 2 | 946, 418, 780, 661, 807 |
| 3 | 473, 209, 390, 661, 807 |
| 11 | 473, 209, 130, 661, 269 |
| 43, 19, 130, 661, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 43 x 19 x 130 x 661 x 269 = 1246416196740
Therefore, the lowest common multiple of 946,418,780,661,807 is 1246416196740.
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.
946 x 418 x 780 x 661 x 807 = 164526937969680
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.
946 : 1, 2, 11, 22, 43, 86, 473, 946
418 : 1, 2, 11, 19, 22, 38, 209, 418
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
661 : 1, 661
807 : 1, 3, 269, 807
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,418,780,661,807, is 1.
Now, the common factors can be found like this.
946:2x 11x 43
418:2x 11x 19
780:2x 2x 3x 5x 13
661:661
807:3x 269
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 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 164526937969680/(1x132)
LCM = 164526937969680/132
LCM = 1246416196740
Thus, we can understand that the LCM of 946,418,780,661,807 is 1246416196740.
