Given numbers are 221,844,398,431,900
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,844,398,431,900 is 3599544815100.
Find LCM of 221,844,398,431,900 with Prime Factorization
| 2 | 221, 844, 398, 431, 900 |
| 2 | 221, 422, 199, 431, 450 |
| 221, 211, 199, 431, 225 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 221 x 211 x 199 x 431 x 225 = 3599544815100
Therefore, the lowest common multiple of 221,844,398,431,900 is 3599544815100.
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 844 x 398 x 431 x 900 = 28796358520800
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
844 : 1, 2, 4, 211, 422, 844
398 : 1, 2, 199, 398
431 : 1, 431
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,844,398,431,900, is 1.
Now, the common factors can be found like this.
221:13x 17
844:2x 2x 211
398:2x 199
431:431
900:2x 2x 3x 3x 5x 5
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 2 = 8
Therefore, the value for common factors is 8.
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 = 28796358520800/(1x8)
LCM = 28796358520800/8
LCM = 3599544815100
Thus, we can understand that the LCM of 221,844,398,431,900 is 3599544815100.
