Given numbers are 423,893,380
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 423,893,380 is 160740.
Find LCM of 423,893,380 with Prime Factorization
| 19 | 423, 893, 380 |
| 47 | 423, 47, 20 |
| 9, 1, 20 |
Multiply the prime numbers at the bottom and the left side.
19 x 47 x 9 x 1 x 20 = 160740
Therefore, the lowest common multiple of 423,893,380 is 160740.
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 893 x 380 = 143540820
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
893 : 1, 19, 47, 893
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,893,380, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
893:19x 47
380:2x 2x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 47 = 893
Therefore, the value for common factors is 893.
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 = 143540820/(1x893)
LCM = 143540820/893
LCM = 160740
Thus, we can understand that the LCM of 423,893,380 is 160740.
