Given numbers are 681,142,806,722,948
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,142,806,722,948 is 2222822536428.
Find LCM of 681,142,806,722,948 with Prime Factorization
| 2 | 681, 142, 806, 722, 948 |
| 3 | 681, 71, 403, 361, 474 |
| 227, 71, 403, 361, 158 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 227 x 71 x 403 x 361 x 158 = 2222822536428
Therefore, the lowest common multiple of 681,142,806,722,948 is 2222822536428.
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 142 x 806 x 722 x 948 = 53347740874272
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
142 : 1, 2, 71, 142
806 : 1, 2, 13, 26, 31, 62, 403, 806
722 : 1, 2, 19, 38, 361, 722
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,142,806,722,948, is 1.
Now, the common factors can be found like this.
681:3x 227
142:2x 71
806:2x 13x 31
722:2x 19x 19
948:2x 2x 3x 79
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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 53347740874272/(1x24)
LCM = 53347740874272/24
LCM = 2222822536428
Thus, we can understand that the LCM of 681,142,806,722,948 is 2222822536428.
