Given numbers are 813,574,829,651
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,574,829,651 is 11992746738.
Find LCM of 813,574,829,651 with Prime Factorization
| 3 | 813, 574, 829, 651 |
| 7 | 271, 574, 829, 217 |
| 271, 82, 829, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 271 x 82 x 829 x 31 = 11992746738
Therefore, the lowest common multiple of 813,574,829,651 is 11992746738.
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.
813 x 574 x 829 x 651 = 251847681498
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.
813 : 1, 3, 271, 813
574 : 1, 2, 7, 14, 41, 82, 287, 574
829 : 1, 829
651 : 1, 3, 7, 21, 31, 93, 217, 651
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,574,829,651, is 1.
Now, the common factors can be found like this.
813:3x 271
574:2x 7x 41
829:829
651:3x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 251847681498/(1x21)
LCM = 251847681498/21
LCM = 11992746738
Thus, we can understand that the LCM of 813,574,829,651 is 11992746738.
