Given numbers are 817,72,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 817,72,817 is 58824.
Find LCM of 817,72,817 with Prime Factorization
| 19 | 817, 72, 817 |
| 43 | 43, 72, 43 |
| 1, 72, 1 |
Multiply the prime numbers at the bottom and the left side.
19 x 43 x 1 x 72 x 1 = 58824
Therefore, the lowest common multiple of 817,72,817 is 58824.
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.
817 x 72 x 817 = 48059208
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.
817 : 1, 19, 43, 817
72 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,72,817, is 1.
Now, the common factors can be found like this.
817:19x 43
72:2x 2x 2x 3x 3
817:19x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 43 = 817
Therefore, the value for common factors is 817.
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 = 48059208/(1x817)
LCM = 48059208/817
LCM = 58824
Thus, we can understand that the LCM of 817,72,817 is 58824.
