Given numbers are 403,989,320,810,131
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,989,320,810,131 is 1353342219840.
Find LCM of 403,989,320,810,131 with Prime Factorization
2 | 403, 989, 320, 810, 131 |
5 | 403, 989, 160, 405, 131 |
403, 989, 32, 81, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 403 x 989 x 32 x 81 x 131 = 1353342219840
Therefore, the lowest common multiple of 403,989,320,810,131 is 1353342219840.
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.
403 x 989 x 320 x 810 x 131 = 13533422198400
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.
403 : 1, 13, 31, 403
989 : 1, 23, 43, 989
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
131 : 1, 131
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,989,320,810,131, is 1.
Now, the common factors can be found like this.
403:13x 31
989:23x 43
320:2x 2x 2x 2x 2x 2x 5
810:2x 3x 3x 3x 3x 5
131:131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 13533422198400/(1x10)
LCM = 13533422198400/10
LCM = 1353342219840
Thus, we can understand that the LCM of 403,989,320,810,131 is 1353342219840.
