Given numbers are 142,646,447,409
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 142,646,447,409 is 8385359718.
Find LCM of 142,646,447,409 with Prime Factorization
2 | 142, 646, 447, 409 |
71, 323, 447, 409 |
Multiply the prime numbers at the bottom and the left side.
2 x 71 x 323 x 447 x 409 = 8385359718
Therefore, the lowest common multiple of 142,646,447,409 is 8385359718.
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.
142 x 646 x 447 x 409 = 16770719436
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.
142 : 1, 2, 71, 142
646 : 1, 2, 17, 19, 34, 38, 323, 646
447 : 1, 3, 149, 447
409 : 1, 409
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,646,447,409, is 1.
Now, the common factors can be found like this.
142:2x 71
646:2x 17x 19
447:3x 149
409:409
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 16770719436/(1x2)
LCM = 16770719436/2
LCM = 8385359718
Thus, we can understand that the LCM of 142,646,447,409 is 8385359718.
