Given numbers are 640,964,622,718,718
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 640,964,622,718,718 is 17220741760.
Find LCM of 640,964,622,718,718 with Prime Factorization
2 | 640, 964, 622, 718, 718 |
2 | 320, 482, 311, 359, 359 |
359 | 160, 241, 311, 359, 359 |
160, 241, 311, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 359 x 160 x 241 x 311 x 1 x 1 = 17220741760
Therefore, the lowest common multiple of 640,964,622,718,718 is 17220741760.
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.
640 x 964 x 622 x 718 x 718 = 197831881338880
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
964 : 1, 2, 4, 241, 482, 964
622 : 1, 2, 311, 622
718 : 1, 2, 359, 718
718 : 1, 2, 359, 718
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,964,622,718,718, is 2.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
964:2x 2x 241
622:2x 311
718:2x 359
718:2x 359
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 359 = 5744
Therefore, the value for common factors is 5744.
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 = 197831881338880/(2x5744)
LCM = 197831881338880/11488
LCM = 17220741760
Thus, we can understand that the LCM of 640,964,622,718,718 is 17220741760.
