Given numbers are 801,630,561,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 801,630,561,418 is 199216710.
Find LCM of 801,630,561,418 with Prime Factorization
| 2 | 801, 630, 561, 418 |
| 3 | 801, 315, 561, 209 |
| 3 | 267, 105, 187, 209 |
| 11 | 89, 35, 187, 209 |
| 89, 35, 17, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 89 x 35 x 17 x 19 = 199216710
Therefore, the lowest common multiple of 801,630,561,418 is 199216710.
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.
801 x 630 x 561 x 418 = 118334725740
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.
801 : 1, 3, 9, 89, 267, 801
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
561 : 1, 3, 11, 17, 33, 51, 187, 561
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 801,630,561,418, is 1.
Now, the common factors can be found like this.
801:3x 3x 89
630:2x 3x 3x 5x 7
561:3x 11x 17
418:2x 11x 19
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 3x 3x 11 = 594
Therefore, the value for common factors is 594.
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 = 118334725740/(1x594)
LCM = 118334725740/594
LCM = 199216710
Thus, we can understand that the LCM of 801,630,561,418 is 199216710.
