Given numbers are 221,621,680,950,863
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,621,680,950,863 is 450068135400.
Find LCM of 221,621,680,950,863 with Prime Factorization
| 2 | 221, 621, 680, 950, 863 |
| 5 | 221, 621, 340, 475, 863 |
| 17 | 221, 621, 68, 95, 863 |
| 13, 621, 4, 95, 863 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 13 x 621 x 4 x 95 x 863 = 450068135400
Therefore, the lowest common multiple of 221,621,680,950,863 is 450068135400.
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.
221 x 621 x 680 x 950 x 863 = 76511583018000
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.
221 : 1, 13, 17, 221
621 : 1, 3, 9, 23, 27, 69, 207, 621
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950
863 : 1, 863
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,621,680,950,863, is 1.
Now, the common factors can be found like this.
221:13x 17
621:3x 3x 3x 23
680:2x 2x 2x 5x 17
950:2x 5x 5x 19
863:863
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 17 = 170
Therefore, the value for common factors is 170.
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 = 76511583018000/(1x170)
LCM = 76511583018000/170
LCM = 450068135400
Thus, we can understand that the LCM of 221,621,680,950,863 is 450068135400.
