Given numbers are 680,923,319,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 680,923,319,442 is 200217160.
Find LCM of 680,923,319,442 with Prime Factorization
| 2 | 680, 923, 319, 442 |
| 13 | 340, 923, 319, 221 |
| 17 | 340, 71, 319, 17 |
| 20, 71, 319, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 20 x 71 x 319 x 1 = 200217160
Therefore, the lowest common multiple of 680,923,319,442 is 200217160.
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.
680 x 923 x 319 x 442 = 88495984720
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.
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
923 : 1, 13, 71, 923
319 : 1, 11, 29, 319
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,923,319,442, is 1.
Now, the common factors can be found like this.
680:2x 2x 2x 5x 17
923:13x 71
319:11x 29
442:2x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 17 = 442
Therefore, the value for common factors is 442.
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 = 88495984720/(1x442)
LCM = 88495984720/442
LCM = 200217160
Thus, we can understand that the LCM of 680,923,319,442 is 200217160.
