Given numbers are 323,668,669,688,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 323,668,669,688,988 is 322757915376.
Find LCM of 323,668,669,688,988 with Prime Factorization
| 2 | 323, 668, 669, 688, 988 |
| 2 | 323, 334, 669, 344, 494 |
| 19 | 323, 167, 669, 172, 247 |
| 17, 167, 669, 172, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 17 x 167 x 669 x 172 x 13 = 322757915376
Therefore, the lowest common multiple of 323,668,669,688,988 is 322757915376.
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.
323 x 668 x 669 x 688 x 988 = 98118406274304
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.
323 : 1, 17, 19, 323
668 : 1, 2, 4, 167, 334, 668
669 : 1, 3, 223, 669
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 323,668,669,688,988, is 1.
Now, the common factors can be found like this.
323:17x 19
668:2x 2x 167
669:3x 223
688:2x 2x 2x 2x 43
988:2x 2x 13x 19
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 19 = 304
Therefore, the value for common factors is 304.
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 = 98118406274304/(1x304)
LCM = 98118406274304/304
LCM = 322757915376
Thus, we can understand that the LCM of 323,668,669,688,988 is 322757915376.
