Given numbers are 874,817,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,817,821 is 30854822.
Find LCM of 874,817,821 with Prime Factorization
19 | 874, 817, 821 |
46, 43, 821 |
Multiply the prime numbers at the bottom and the left side.
19 x 46 x 43 x 821 = 30854822
Therefore, the lowest common multiple of 874,817,821 is 30854822.
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.
874 x 817 x 821 = 586241618
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
817 : 1, 19, 43, 817
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,817,821, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
817:19x 43
821:821
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 586241618/(1x19)
LCM = 586241618/19
LCM = 30854822
Thus, we can understand that the LCM of 874,817,821 is 30854822.
