Given numbers are 668,572,863,492
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,572,863,492 is 10139777076.
Find LCM of 668,572,863,492 with Prime Factorization
| 2 | 668, 572, 863, 492 |
| 2 | 334, 286, 863, 246 |
| 167, 143, 863, 123 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 167 x 143 x 863 x 123 = 10139777076
Therefore, the lowest common multiple of 668,572,863,492 is 10139777076.
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 572 x 863 x 492 = 162236433216
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
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
863 : 1, 863
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,572,863,492, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
572:2x 2x 11x 13
863:863
492:2x 2x 3x 41
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 2 = 16
Therefore, the value for common factors is 16.
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 = 162236433216/(1x16)
LCM = 162236433216/16
LCM = 10139777076
Thus, we can understand that the LCM of 668,572,863,492 is 10139777076.
