Given numbers are 164,370,817,991,814
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 164,370,817,991,814 is 270211589780.
Find LCM of 164,370,817,991,814 with Prime Factorization
| 2 | 164, 370, 817, 991, 814 |
| 37 | 82, 185, 817, 991, 407 |
| 82, 5, 817, 991, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 37 x 82 x 5 x 817 x 991 x 11 = 270211589780
Therefore, the lowest common multiple of 164,370,817,991,814 is 270211589780.
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.
164 x 370 x 817 x 991 x 814 = 39991315287440
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.
164 : 1, 2, 4, 41, 82, 164
370 : 1, 2, 5, 10, 37, 74, 185, 370
817 : 1, 19, 43, 817
991 : 1, 991
814 : 1, 2, 11, 22, 37, 74, 407, 814
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 164,370,817,991,814, is 1.
Now, the common factors can be found like this.
164:2x 2x 41
370:2x 5x 37
817:19x 43
991:991
814:2x 11x 37
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 37 = 148
Therefore, the value for common factors is 148.
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 = 39991315287440/(1x148)
LCM = 39991315287440/148
LCM = 270211589780
Thus, we can understand that the LCM of 164,370,817,991,814 is 270211589780.
