Given numbers are 331,626,662,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 331,626,662,688 is 71278864.
Find LCM of 331,626,662,688 with Prime Factorization
| 2 | 331, 626, 662, 688 |
| 331 | 331, 313, 331, 344 |
| 1, 313, 1, 344 |
Multiply the prime numbers at the bottom and the left side.
2 x 331 x 1 x 313 x 1 x 344 = 71278864
Therefore, the lowest common multiple of 331,626,662,688 is 71278864.
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.
331 x 626 x 662 x 688 = 94373215936
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.
331 : 1, 331
626 : 1, 2, 313, 626
662 : 1, 2, 331, 662
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,626,662,688, is 1.
Now, the common factors can be found like this.
331:331
626:2x 313
662:2x 331
688:2x 2x 2x 2x 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 331 = 1324
Therefore, the value for common factors is 1324.
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 = 94373215936/(1x1324)
LCM = 94373215936/1324
LCM = 71278864
Thus, we can understand that the LCM of 331,626,662,688 is 71278864.
