Given numbers are 817,405,902,893
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 817,405,902,893 is 14027538690.
Find LCM of 817,405,902,893 with Prime Factorization
19 | 817, 405, 902, 893 |
43, 405, 902, 47 |
Multiply the prime numbers at the bottom and the left side.
19 x 43 x 405 x 902 x 47 = 14027538690
Therefore, the lowest common multiple of 817,405,902,893 is 14027538690.
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.
817 x 405 x 902 x 893 = 266523235110
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.
817 : 1, 19, 43, 817
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
902 : 1, 2, 11, 22, 41, 82, 451, 902
893 : 1, 19, 47, 893
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,405,902,893, is 1.
Now, the common factors can be found like this.
817:19x 43
405:3x 3x 3x 3x 5
902:2x 11x 41
893:19x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 266523235110/(1x19)
LCM = 266523235110/19
LCM = 14027538690
Thus, we can understand that the LCM of 817,405,902,893 is 14027538690.
