Given numbers are 669,912,446,878
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,912,446,878 is 89282064.
Find LCM of 669,912,446,878 with Prime Factorization
| 2 | 669, 912, 446, 878 |
| 3 | 669, 456, 223, 439 |
| 223 | 223, 152, 223, 439 |
| 1, 152, 1, 439 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 223 x 1 x 152 x 1 x 439 = 89282064
Therefore, the lowest common multiple of 669,912,446,878 is 89282064.
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 912 x 446 x 878 = 238918803264
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
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
446 : 1, 2, 223, 446
878 : 1, 2, 439, 878
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,912,446,878, is 1.
Now, the common factors can be found like this.
669:3x 223
912:2x 2x 2x 2x 3x 19
446:2x 223
878:2x 439
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 3x 223 = 2676
Therefore, the value for common factors is 2676.
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 = 238918803264/(1x2676)
LCM = 238918803264/2676
LCM = 89282064
Thus, we can understand that the LCM of 669,912,446,878 is 89282064.
