Given numbers are 221,845,894
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,845,894 is 12842310.
Find LCM of 221,845,894 with Prime Factorization
13 | 221, 845, 894 |
17, 65, 894 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 65 x 894 = 12842310
Therefore, the lowest common multiple of 221,845,894 is 12842310.
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 845 x 894 = 166950030
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
845 : 1, 5, 13, 65, 169, 845
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,845,894, is 1.
Now, the common factors can be found like this.
221:13x 17
845:5x 13x 13
894:2x 3x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 166950030/(1x13)
LCM = 166950030/13
LCM = 12842310
Thus, we can understand that the LCM of 221,845,894 is 12842310.
