Given numbers are 279,587,806,140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 279,587,806,140 is 298066860.
Find LCM of 279,587,806,140 with Prime Factorization
| 2 | 279, 587, 806, 140 |
| 31 | 279, 587, 403, 70 |
| 9, 587, 13, 70 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 9 x 587 x 13 x 70 = 298066860
Therefore, the lowest common multiple of 279,587,806,140 is 298066860.
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.
279 x 587 x 806 x 140 = 18480145320
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.
279 : 1, 3, 9, 31, 93, 279
587 : 1, 587
806 : 1, 2, 13, 26, 31, 62, 403, 806
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,587,806,140, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
587:587
806:2x 13x 31
140:2x 2x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 31 = 62
Therefore, the value for common factors is 62.
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 = 18480145320/(1x62)
LCM = 18480145320/62
LCM = 298066860
Thus, we can understand that the LCM of 279,587,806,140 is 298066860.
