Given numbers are 305,451,565,116,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 305,451,565,116,870 is 5409212820.
Find LCM of 305,451,565,116,870 with Prime Factorization
| 2 | 305, 451, 565, 116, 870 |
| 5 | 305, 451, 565, 58, 435 |
| 29 | 61, 451, 113, 58, 87 |
| 61, 451, 113, 2, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 29 x 61 x 451 x 113 x 2 x 3 = 5409212820
Therefore, the lowest common multiple of 305,451,565,116,870 is 5409212820.
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.
305 x 451 x 565 x 116 x 870 = 7843358589000
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.
305 : 1, 5, 61, 305
451 : 1, 11, 41, 451
565 : 1, 5, 113, 565
116 : 1, 2, 4, 29, 58, 116
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,451,565,116,870, is 1.
Now, the common factors can be found like this.
305:5x 61
451:11x 41
565:5x 113
116:2x 2x 29
870:2x 3x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 29 = 1450
Therefore, the value for common factors is 1450.
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 = 7843358589000/(1x1450)
LCM = 7843358589000/1450
LCM = 5409212820
Thus, we can understand that the LCM of 305,451,565,116,870 is 5409212820.
