Given numbers are 253,418,423,705
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 253,418,423,705 is 20333610.
Find LCM of 253,418,423,705 with Prime Factorization
| 3 | 253, 418, 423, 705 |
| 11 | 253, 418, 141, 235 |
| 47 | 23, 38, 141, 235 |
| 23, 38, 3, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 47 x 23 x 38 x 3 x 5 = 20333610
Therefore, the lowest common multiple of 253,418,423,705 is 20333610.
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.
253 x 418 x 423 x 705 = 31537429110
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.
253 : 1, 11, 23, 253
418 : 1, 2, 11, 19, 22, 38, 209, 418
423 : 1, 3, 9, 47, 141, 423
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,418,423,705, is 1.
Now, the common factors can be found like this.
253:11x 23
418:2x 11x 19
423:3x 3x 47
705:3x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 47 = 1551
Therefore, the value for common factors is 1551.
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 = 31537429110/(1x1551)
LCM = 31537429110/1551
LCM = 20333610
Thus, we can understand that the LCM of 253,418,423,705 is 20333610.
