Given numbers are 668,409,893,704
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,409,893,704 is 42940183616.
Find LCM of 668,409,893,704 with Prime Factorization
| 2 | 668, 409, 893, 704 |
| 2 | 334, 409, 893, 352 |
| 167, 409, 893, 176 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 167 x 409 x 893 x 176 = 42940183616
Therefore, the lowest common multiple of 668,409,893,704 is 42940183616.
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.
668 x 409 x 893 x 704 = 171760734464
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.
668 : 1, 2, 4, 167, 334, 668
409 : 1, 409
893 : 1, 19, 47, 893
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,409,893,704, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
409:409
893:19x 47
704:2x 2x 2x 2x 2x 2x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 171760734464/(1x4)
LCM = 171760734464/4
LCM = 42940183616
Thus, we can understand that the LCM of 668,409,893,704 is 42940183616.
