Given numbers are 668,329,817,529,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,329,817,529,861 is 11683022159508.
Find LCM of 668,329,817,529,861 with Prime Factorization
| 7 | 668, 329, 817, 529, 861 |
| 668, 47, 817, 529, 123 |
Multiply the prime numbers at the bottom and the left side.
7 x 668 x 47 x 817 x 529 x 123 = 11683022159508
Therefore, the lowest common multiple of 668,329,817,529,861 is 11683022159508.
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 329 x 817 x 529 x 861 = 81781155116556
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
329 : 1, 7, 47, 329
817 : 1, 19, 43, 817
529 : 1, 23, 529
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,329,817,529,861, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
329:7x 47
817:19x 43
529:23x 23
861:3x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 81781155116556/(1x7)
LCM = 81781155116556/7
LCM = 11683022159508
Thus, we can understand that the LCM of 668,329,817,529,861 is 11683022159508.
