Given numbers are 423,831,377,403,556
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 423,831,377,403,556 is 761373877212.
Find LCM of 423,831,377,403,556 with Prime Factorization
| 3 | 423, 831, 377, 403, 556 |
| 13 | 141, 277, 377, 403, 556 |
| 141, 277, 29, 31, 556 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 141 x 277 x 29 x 31 x 556 = 761373877212
Therefore, the lowest common multiple of 423,831,377,403,556 is 761373877212.
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.
423 x 831 x 377 x 403 x 556 = 29693581211268
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.
423 : 1, 3, 9, 47, 141, 423
831 : 1, 3, 277, 831
377 : 1, 13, 29, 377
403 : 1, 13, 31, 403
556 : 1, 2, 4, 139, 278, 556
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,831,377,403,556, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
831:3x 277
377:13x 29
403:13x 31
556:2x 2x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 29693581211268/(1x39)
LCM = 29693581211268/39
LCM = 761373877212
Thus, we can understand that the LCM of 423,831,377,403,556 is 761373877212.
