Given numbers are 640,574,484,629
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 640,574,484,629 is 13979701120.
Find LCM of 640,574,484,629 with Prime Factorization
2 | 640, 574, 484, 629 |
2 | 320, 287, 242, 629 |
160, 287, 121, 629 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 160 x 287 x 121 x 629 = 13979701120
Therefore, the lowest common multiple of 640,574,484,629 is 13979701120.
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 574 x 484 x 629 = 111837608960
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
574 : 1, 2, 7, 14, 41, 82, 287, 574
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
629 : 1, 17, 37, 629
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,574,484,629, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
574:2x 7x 41
484:2x 2x 11x 11
629:17x 37
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 = 111837608960/(1x8)
LCM = 111837608960/8
LCM = 13979701120
Thus, we can understand that the LCM of 640,574,484,629 is 13979701120.
