Given numbers are 380,687,652,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 380,687,652,618 is 4382936340.
Find LCM of 380,687,652,618 with Prime Factorization
| 2 | 380, 687, 652, 618 |
| 2 | 190, 687, 326, 309 |
| 3 | 95, 687, 163, 309 |
| 95, 229, 163, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 95 x 229 x 163 x 103 = 4382936340
Therefore, the lowest common multiple of 380,687,652,618 is 4382936340.
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.
380 x 687 x 652 x 618 = 105190472160
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
687 : 1, 3, 229, 687
652 : 1, 2, 4, 163, 326, 652
618 : 1, 2, 3, 6, 103, 206, 309, 618
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,687,652,618, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
687:3x 229
652:2x 2x 163
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 2x 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 105190472160/(1x24)
LCM = 105190472160/24
LCM = 4382936340
Thus, we can understand that the LCM of 380,687,652,618 is 4382936340.
