Given numbers are 813,507,786,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,507,786,618 is 3707795442.
Find LCM of 813,507,786,618 with Prime Factorization
| 2 | 813, 507, 786, 618 |
| 3 | 813, 507, 393, 309 |
| 271, 169, 131, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 271 x 169 x 131 x 103 = 3707795442
Therefore, the lowest common multiple of 813,507,786,618 is 3707795442.
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 507 x 786 x 618 = 200220953868
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
507 : 1, 3, 13, 39, 169, 507
786 : 1, 2, 3, 6, 131, 262, 393, 786
618 : 1, 2, 3, 6, 103, 206, 309, 618
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,507,786,618, is 3.
Now, the common factors can be found like this.
813:3x 271
507:3x 13x 13
786:2x 3x 131
618:2x 3x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 200220953868/(3x18)
LCM = 200220953868/54
LCM = 3707795442
Thus, we can understand that the LCM of 813,507,786,618 is 3707795442.
