Given numbers are 946,676,143,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 946,676,143,781 is 22702108.
Find LCM of 946,676,143,781 with Prime Factorization
| 2 | 946, 676, 143, 781 |
| 11 | 473, 338, 143, 781 |
| 13 | 43, 338, 13, 71 |
| 43, 26, 1, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 43 x 26 x 1 x 71 = 22702108
Therefore, the lowest common multiple of 946,676,143,781 is 22702108.
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 676 x 143 x 781 = 71420831768
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
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
143 : 1, 11, 13, 143
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,676,143,781, is 1.
Now, the common factors can be found like this.
946:2x 11x 43
676:2x 2x 13x 13
143:11x 13
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11x 13 = 3146
Therefore, the value for common factors is 3146.
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 = 71420831768/(1x3146)
LCM = 71420831768/3146
LCM = 22702108
Thus, we can understand that the LCM of 946,676,143,781 is 22702108.
