Given numbers are 855,988,342,426,633
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,988,342,426,633 is 666055260.
Find LCM of 855,988,342,426,633 with Prime Factorization
| 2 | 855, 988, 342, 426, 633 |
| 3 | 855, 494, 171, 213, 633 |
| 3 | 285, 494, 57, 71, 211 |
| 19 | 95, 494, 19, 71, 211 |
| 5, 26, 1, 71, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 19 x 5 x 26 x 1 x 71 x 211 = 666055260
Therefore, the lowest common multiple of 855,988,342,426,633 is 666055260.
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.
855 x 988 x 342 x 426 x 633 = 77904487430640
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
426 : 1, 2, 3, 6, 71, 142, 213, 426
633 : 1, 3, 211, 633
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,988,342,426,633, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
988:2x 2x 13x 19
342:2x 3x 3x 19
426:2x 3x 71
633:3x 211
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 3x 3x 3x 3x 19x 19 = 116964
Therefore, the value for common factors is 116964.
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 = 77904487430640/(1x116964)
LCM = 77904487430640/116964
LCM = 666055260
Thus, we can understand that the LCM of 855,988,342,426,633 is 666055260.
