Given numbers are 423,452,996,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 423,452,996,221 is 3507108228.
Find LCM of 423,452,996,221 with Prime Factorization
| 2 | 423, 452, 996, 221 |
| 2 | 423, 226, 498, 221 |
| 3 | 423, 113, 249, 221 |
| 141, 113, 83, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 141 x 113 x 83 x 221 = 3507108228
Therefore, the lowest common multiple of 423,452,996,221 is 3507108228.
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 452 x 996 x 221 = 42085298736
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
452 : 1, 2, 4, 113, 226, 452
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,452,996,221, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
452:2x 2x 113
996:2x 2x 3x 83
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3 = 12
Therefore, the value for common factors is 12.
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 = 42085298736/(1x12)
LCM = 42085298736/12
LCM = 3507108228
Thus, we can understand that the LCM of 423,452,996,221 is 3507108228.
