Given numbers are 698,964,800,465,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 698,964,800,465,642 is 669574927200.
Find LCM of 698,964,800,465,642 with Prime Factorization
| 2 | 698, 964, 800, 465, 642 |
| 2 | 349, 482, 400, 465, 321 |
| 3 | 349, 241, 200, 465, 321 |
| 5 | 349, 241, 200, 155, 107 |
| 349, 241, 40, 31, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 349 x 241 x 40 x 31 x 107 = 669574927200
Therefore, the lowest common multiple of 698,964,800,465,642 is 669574927200.
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 964 x 800 x 465 x 642 = 160697982528000
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
964 : 1, 2, 4, 241, 482, 964
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
465 : 1, 3, 5, 15, 31, 93, 155, 465
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,964,800,465,642, is 1.
Now, the common factors can be found like this.
698:2x 349
964:2x 2x 241
800:2x 2x 2x 2x 2x 5x 5
465:3x 5x 31
642:2x 3x 107
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 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 160697982528000/(1x240)
LCM = 160697982528000/240
LCM = 669574927200
Thus, we can understand that the LCM of 698,964,800,465,642 is 669574927200.
