Given numbers are 669,818,171,662,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,818,171,662,946 is 4883637407022.
Find LCM of 669,818,171,662,946 with Prime Factorization
| 2 | 669, 818, 171, 662, 946 |
| 3 | 669, 409, 171, 331, 473 |
| 223, 409, 57, 331, 473 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 223 x 409 x 57 x 331 x 473 = 4883637407022
Therefore, the lowest common multiple of 669,818,171,662,946 is 4883637407022.
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.
669 x 818 x 171 x 662 x 946 = 58603648884264
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.
669 : 1, 3, 223, 669
818 : 1, 2, 409, 818
171 : 1, 3, 9, 19, 57, 171
662 : 1, 2, 331, 662
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,818,171,662,946, is 1.
Now, the common factors can be found like this.
669:3x 223
818:2x 409
171:3x 3x 19
662:2x 331
946:2x 11x 43
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 3 = 12
Therefore, the value for common factors is 12.
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 = 58603648884264/(1x12)
LCM = 58603648884264/12
LCM = 4883637407022
Thus, we can understand that the LCM of 669,818,171,662,946 is 4883637407022.
