Given numbers are 7,657,813,803
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,657,813,803 is 13709619.
Find LCM of 7,657,813,803 with Prime Factorization
| 3 | 7, 657, 813, 803 |
| 73 | 7, 219, 271, 803 |
| 7, 3, 271, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 73 x 7 x 3 x 271 x 11 = 13709619
Therefore, the lowest common multiple of 7,657,813,803 is 13709619.
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.
7 x 657 x 813 x 803 = 3002406561
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.
7 : 1, 7
657 : 1, 3, 9, 73, 219, 657
813 : 1, 3, 271, 813
803 : 1, 11, 73, 803
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,657,813,803, is 1.
Now, the common factors can be found like this.
7:7
657:3x 3x 73
813:3x 271
803:11x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 73 = 219
Therefore, the value for common factors is 219.
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 = 3002406561/(1x219)
LCM = 3002406561/219
LCM = 13709619
Thus, we can understand that the LCM of 7,657,813,803 is 13709619.
