Given numbers are 668,752,531,136,863
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,752,531,136,863 is 978337160784.
Find LCM of 668,752,531,136,863 with Prime Factorization
| 2 | 668, 752, 531, 136, 863 |
| 2 | 334, 376, 531, 68, 863 |
| 2 | 167, 188, 531, 34, 863 |
| 167, 94, 531, 17, 863 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 167 x 94 x 531 x 17 x 863 = 978337160784
Therefore, the lowest common multiple of 668,752,531,136,863 is 978337160784.
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 752 x 531 x 136 x 863 = 31306789145088
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
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
531 : 1, 3, 9, 59, 177, 531
136 : 1, 2, 4, 8, 17, 34, 68, 136
863 : 1, 863
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,752,531,136,863, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
752:2x 2x 2x 2x 47
531:3x 3x 59
136:2x 2x 2x 17
863:863
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 2x 2x 2 = 32
Therefore, the value for common factors is 32.
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 = 31306789145088/(1x32)
LCM = 31306789145088/32
LCM = 978337160784
Thus, we can understand that the LCM of 668,752,531,136,863 is 978337160784.
