Given numbers are 821,813,288,399,350
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,813,288,399,350 is 213057381600.
Find LCM of 821,813,288,399,350 with Prime Factorization
| 2 | 821, 813, 288, 399, 350 |
| 3 | 821, 813, 144, 399, 175 |
| 7 | 821, 271, 48, 133, 175 |
| 821, 271, 48, 19, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 821 x 271 x 48 x 19 x 25 = 213057381600
Therefore, the lowest common multiple of 821,813,288,399,350 is 213057381600.
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.
821 x 813 x 288 x 399 x 350 = 26845230081600
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.
821 : 1, 821
813 : 1, 3, 271, 813
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
399 : 1, 3, 7, 19, 21, 57, 133, 399
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,813,288,399,350, is 1.
Now, the common factors can be found like this.
821:821
813:3x 271
288:2x 2x 2x 2x 2x 3x 3
399:3x 7x 19
350:2x 5x 5x 7
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 7 = 126
Therefore, the value for common factors is 126.
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 = 26845230081600/(1x126)
LCM = 26845230081600/126
LCM = 213057381600
Thus, we can understand that the LCM of 821,813,288,399,350 is 213057381600.
