Given numbers are 430,858,638,551
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 430,858,638,551 is 101642970.
Find LCM of 430,858,638,551 with Prime Factorization
2 | 430, 858, 638, 551 |
11 | 215, 429, 319, 551 |
29 | 215, 39, 29, 551 |
215, 39, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 215 x 39 x 1 x 19 = 101642970
Therefore, the lowest common multiple of 430,858,638,551 is 101642970.
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.
430 x 858 x 638 x 551 = 129696429720
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.
430 : 1, 2, 5, 10, 43, 86, 215, 430
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
638 : 1, 2, 11, 22, 29, 58, 319, 638
551 : 1, 19, 29, 551
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 430,858,638,551, is 1.
Now, the common factors can be found like this.
430:2x 5x 43
858:2x 3x 11x 13
638:2x 11x 29
551:19x 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 2x 11x 29 = 1276
Therefore, the value for common factors is 1276.
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 = 129696429720/(1x1276)
LCM = 129696429720/1276
LCM = 101642970
Thus, we can understand that the LCM of 430,858,638,551 is 101642970.
