Given numbers are 857,346,865,905,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 857,346,865,905,931 is 249836093710.
Find LCM of 857,346,865,905,931 with Prime Factorization
5 | 857, 346, 865, 905, 931 |
173 | 857, 346, 173, 181, 931 |
857, 2, 1, 181, 931 |
Multiply the prime numbers at the bottom and the left side.
5 x 173 x 857 x 2 x 1 x 181 x 931 = 249836093710
Therefore, the lowest common multiple of 857,346,865,905,931 is 249836093710.
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.
857 x 346 x 865 x 905 x 931 = 216108221059150
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.
857 : 1, 857
346 : 1, 2, 173, 346
865 : 1, 5, 173, 865
905 : 1, 5, 181, 905
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 857,346,865,905,931, is 1.
Now, the common factors can be found like this.
857:857
346:2x 173
865:5x 173
905:5x 181
931:7x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 173 = 865
Therefore, the value for common factors is 865.
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 = 216108221059150/(1x865)
LCM = 216108221059150/865
LCM = 249836093710
Thus, we can understand that the LCM of 857,346,865,905,931 is 249836093710.
