Given numbers are 509,618,980,451,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 509,618,980,451,820 is 69515056380.
Find LCM of 509,618,980,451,820 with Prime Factorization
| 2 | 509, 618, 980, 451, 820 |
| 2 | 509, 309, 490, 451, 410 |
| 5 | 509, 309, 245, 451, 205 |
| 41 | 509, 309, 49, 451, 41 |
| 509, 309, 49, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 41 x 509 x 309 x 49 x 11 x 1 = 69515056380
Therefore, the lowest common multiple of 509,618,980,451,820 is 69515056380.
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.
509 x 618 x 980 x 451 x 820 = 114004692463200
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.
509 : 1, 509
618 : 1, 2, 3, 6, 103, 206, 309, 618
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
451 : 1, 11, 41, 451
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 509,618,980,451,820, is 1.
Now, the common factors can be found like this.
509:509
618:2x 3x 103
980:2x 2x 5x 7x 7
451:11x 41
820:2x 2x 5x 41
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 5x 41 = 1640
Therefore, the value for common factors is 1640.
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 = 114004692463200/(1x1640)
LCM = 114004692463200/1640
LCM = 69515056380
Thus, we can understand that the LCM of 509,618,980,451,820 is 69515056380.
