Given numbers are 681,707,956,351
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,707,956,351 is 53853046884.
Find LCM of 681,707,956,351 with Prime Factorization
| 3 | 681, 707, 956, 351 |
| 227, 707, 956, 117 |
Multiply the prime numbers at the bottom and the left side.
3 x 227 x 707 x 956 x 117 = 53853046884
Therefore, the lowest common multiple of 681,707,956,351 is 53853046884.
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.
681 x 707 x 956 x 351 = 161559140652
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.
681 : 1, 3, 227, 681
707 : 1, 7, 101, 707
956 : 1, 2, 4, 239, 478, 956
351 : 1, 3, 9, 13, 27, 39, 117, 351
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,707,956,351, is 1.
Now, the common factors can be found like this.
681:3x 227
707:7x 101
956:2x 2x 239
351:3x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 161559140652/(1x3)
LCM = 161559140652/3
LCM = 53853046884
Thus, we can understand that the LCM of 681,707,956,351 is 53853046884.
