Given numbers are 656,319,742,203,261
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 656,319,742,203,261 is 698732496.
Find LCM of 656,319,742,203,261 with Prime Factorization
| 2 | 656, 319, 742, 203, 261 |
| 7 | 328, 319, 371, 203, 261 |
| 29 | 328, 319, 53, 29, 261 |
| 328, 11, 53, 1, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 29 x 328 x 11 x 53 x 1 x 9 = 698732496
Therefore, the lowest common multiple of 656,319,742,203,261 is 698732496.
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.
656 x 319 x 742 x 203 x 261 = 8226876407904
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.
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
319 : 1, 11, 29, 319
742 : 1, 2, 7, 14, 53, 106, 371, 742
203 : 1, 7, 29, 203
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 656,319,742,203,261, is 1.
Now, the common factors can be found like this.
656:2x 2x 2x 2x 41
319:11x 29
742:2x 7x 53
203:7x 29
261:3x 3x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 29x 29 = 11774
Therefore, the value for common factors is 11774.
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 = 8226876407904/(1x11774)
LCM = 8226876407904/11774
LCM = 698732496
Thus, we can understand that the LCM of 656,319,742,203,261 is 698732496.
