Given numbers are 698,680,305,730,471
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 698,680,305,730,471 is 497746187160.
Find LCM of 698,680,305,730,471 with Prime Factorization
| 2 | 698, 680, 305, 730, 471 |
| 5 | 349, 340, 305, 365, 471 |
| 349, 68, 61, 73, 471 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 349 x 68 x 61 x 73 x 471 = 497746187160
Therefore, the lowest common multiple of 698,680,305,730,471 is 497746187160.
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.
698 x 680 x 305 x 730 x 471 = 49774618716000
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.
698 : 1, 2, 349, 698
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
305 : 1, 5, 61, 305
730 : 1, 2, 5, 10, 73, 146, 365, 730
471 : 1, 3, 157, 471
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,680,305,730,471, is 1.
Now, the common factors can be found like this.
698:2x 349
680:2x 2x 2x 5x 17
305:5x 61
730:2x 5x 73
471:3x 157
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 49774618716000/(1x100)
LCM = 49774618716000/100
LCM = 497746187160
Thus, we can understand that the LCM of 698,680,305,730,471 is 497746187160.
