Given numbers are 479,620,115,789
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 479,620,115,789 is 5389296060.
Find LCM of 479,620,115,789 with Prime Factorization
| 5 | 479, 620, 115, 789 |
| 479, 124, 23, 789 |
Multiply the prime numbers at the bottom and the left side.
5 x 479 x 124 x 23 x 789 = 5389296060
Therefore, the lowest common multiple of 479,620,115,789 is 5389296060.
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.
479 x 620 x 115 x 789 = 26946480300
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.
479 : 1, 479
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
115 : 1, 5, 23, 115
789 : 1, 3, 263, 789
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 479,620,115,789, is 1.
Now, the common factors can be found like this.
479:479
620:2x 2x 5x 31
115:5x 23
789:3x 263
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 26946480300/(1x5)
LCM = 26946480300/5
LCM = 5389296060
Thus, we can understand that the LCM of 479,620,115,789 is 5389296060.
