Given numbers are 694,662,688,129
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 694,662,688,129 is 237064848.
Find LCM of 694,662,688,129 with Prime Factorization
| 2 | 694, 662, 688, 129 |
| 43 | 347, 331, 344, 129 |
| 347, 331, 8, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 43 x 347 x 331 x 8 x 3 = 237064848
Therefore, the lowest common multiple of 694,662,688,129 is 237064848.
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.
694 x 662 x 688 x 129 = 40775153856
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.
694 : 1, 2, 347, 694
662 : 1, 2, 331, 662
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 694,662,688,129, is 1.
Now, the common factors can be found like this.
694:2x 347
662:2x 331
688:2x 2x 2x 2x 43
129:3x 43
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 43 = 172
Therefore, the value for common factors is 172.
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 = 40775153856/(1x172)
LCM = 40775153856/172
LCM = 237064848
Thus, we can understand that the LCM of 694,662,688,129 is 237064848.
