Given numbers are 698,828,662,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 698,828,662,688 is 16451753904.
Find LCM of 698,828,662,688 with Prime Factorization
2 | 698, 828, 662, 688 |
2 | 349, 414, 331, 344 |
349, 207, 331, 172 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 349 x 207 x 331 x 172 = 16451753904
Therefore, the lowest common multiple of 698,828,662,688 is 16451753904.
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.
698 x 828 x 662 x 688 = 263228062464
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.
698 : 1, 2, 349, 698
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
662 : 1, 2, 331, 662
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,828,662,688, is 2.
Now, the common factors can be found like this.
698:2x 349
828:2x 2x 3x 3x 23
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 2 = 8
Therefore, the value for common factors is 8.
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 = 263228062464/(2x8)
LCM = 263228062464/16
LCM = 16451753904
Thus, we can understand that the LCM of 698,828,662,688 is 16451753904.
