Given numbers are 281,678,143,868,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 281,678,143,868,781 is 839498896236.
Find LCM of 281,678,143,868,781 with Prime Factorization
2 | 281, 678, 143, 868, 781 |
11 | 281, 339, 143, 434, 781 |
281, 339, 13, 434, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 281 x 339 x 13 x 434 x 71 = 839498896236
Therefore, the lowest common multiple of 281,678,143,868,781 is 839498896236.
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.
281 x 678 x 143 x 868 x 781 = 18468975717192
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.
281 : 1, 281
678 : 1, 2, 3, 6, 113, 226, 339, 678
143 : 1, 11, 13, 143
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,678,143,868,781, is 1.
Now, the common factors can be found like this.
281:281
678:2x 3x 113
143:11x 13
868:2x 2x 7x 31
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 11 = 22
Therefore, the value for common factors is 22.
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 = 18468975717192/(1x22)
LCM = 18468975717192/22
LCM = 839498896236
Thus, we can understand that the LCM of 281,678,143,868,781 is 839498896236.
