Given numbers are 319,880,710,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 319,880,710,721 is 1306394320.
Find LCM of 319,880,710,721 with Prime Factorization
| 2 | 319, 880, 710, 721 |
| 5 | 319, 440, 355, 721 |
| 11 | 319, 88, 71, 721 |
| 29, 8, 71, 721 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 29 x 8 x 71 x 721 = 1306394320
Therefore, the lowest common multiple of 319,880,710,721 is 1306394320.
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.
319 x 880 x 710 x 721 = 143703375200
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.
319 : 1, 11, 29, 319
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
710 : 1, 2, 5, 10, 71, 142, 355, 710
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 319,880,710,721, is 1.
Now, the common factors can be found like this.
319:11x 29
880:2x 2x 2x 2x 5x 11
710:2x 5x 71
721:7x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 143703375200/(1x110)
LCM = 143703375200/110
LCM = 1306394320
Thus, we can understand that the LCM of 319,880,710,721 is 1306394320.
