Given numbers are 874,660,638,403,956
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,660,638,403,956 is 805612725060.
Find LCM of 874,660,638,403,956 with Prime Factorization
| 2 | 874, 660, 638, 403, 956 |
| 2 | 437, 330, 319, 403, 478 |
| 11 | 437, 165, 319, 403, 239 |
| 437, 15, 29, 403, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 437 x 15 x 29 x 403 x 239 = 805612725060
Therefore, the lowest common multiple of 874,660,638,403,956 is 805612725060.
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.
874 x 660 x 638 x 403 x 956 = 141787839610560
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
638 : 1, 2, 11, 22, 29, 58, 319, 638
403 : 1, 13, 31, 403
956 : 1, 2, 4, 239, 478, 956
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,660,638,403,956, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
660:2x 2x 3x 5x 11
638:2x 11x 29
403:13x 31
956:2x 2x 239
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 11 = 176
Therefore, the value for common factors is 176.
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 = 141787839610560/(1x176)
LCM = 141787839610560/176
LCM = 805612725060
Thus, we can understand that the LCM of 874,660,638,403,956 is 805612725060.
