Given numbers are 698,801,255,199,170
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 698,801,255,199,170 is 9457142670.
Find LCM of 698,801,255,199,170 with Prime Factorization
| 2 | 698, 801, 255, 199, 170 |
| 3 | 349, 801, 255, 199, 85 |
| 5 | 349, 267, 85, 199, 85 |
| 17 | 349, 267, 17, 199, 17 |
| 349, 267, 1, 199, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 349 x 267 x 1 x 199 x 1 = 9457142670
Therefore, the lowest common multiple of 698,801,255,199,170 is 9457142670.
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 801 x 255 x 199 x 170 = 4823142761700
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
801 : 1, 3, 9, 89, 267, 801
255 : 1, 3, 5, 15, 17, 51, 85, 255
199 : 1, 199
170 : 1, 2, 5, 10, 17, 34, 85, 170
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,801,255,199,170, is 1.
Now, the common factors can be found like this.
698:2x 349
801:3x 3x 89
255:3x 5x 17
199:199
170:2x 5x 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 3x 5x 17 = 510
Therefore, the value for common factors is 510.
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 = 4823142761700/(1x510)
LCM = 4823142761700/510
LCM = 9457142670
Thus, we can understand that the LCM of 698,801,255,199,170 is 9457142670.
