Given numbers are 821,969,258,323
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,969,258,323 is 68417214.
Find LCM of 821,969,258,323 with Prime Factorization
3 | 821, 969, 258, 323 |
17 | 821, 323, 86, 323 |
19 | 821, 19, 86, 19 |
821, 1, 86, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 19 x 821 x 1 x 86 x 1 = 68417214
Therefore, the lowest common multiple of 821,969,258,323 is 68417214.
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 969 x 258 x 323 = 66296280366
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
969 : 1, 3, 17, 19, 51, 57, 323, 969
258 : 1, 2, 3, 6, 43, 86, 129, 258
323 : 1, 17, 19, 323
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,969,258,323, is 1.
Now, the common factors can be found like this.
821:821
969:3x 17x 19
258:2x 3x 43
323:17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17x 19 = 969
Therefore, the value for common factors is 969.
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 = 66296280366/(1x969)
LCM = 66296280366/969
LCM = 68417214
Thus, we can understand that the LCM of 821,969,258,323 is 68417214.
