Given numbers are 215,298,860,435,722
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 215,298,860,435,722 is 4024492980.
Find LCM of 215,298,860,435,722 with Prime Factorization
| 2 | 215, 298, 860, 435, 722 |
| 5 | 215, 149, 430, 435, 361 |
| 43 | 43, 149, 86, 87, 361 |
| 1, 149, 2, 87, 361 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 43 x 1 x 149 x 2 x 87 x 361 = 4024492980
Therefore, the lowest common multiple of 215,298,860,435,722 is 4024492980.
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.
215 x 298 x 860 x 435 x 722 = 17305319814000
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.
215 : 1, 5, 43, 215
298 : 1, 2, 149, 298
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
435 : 1, 3, 5, 15, 29, 87, 145, 435
722 : 1, 2, 19, 38, 361, 722
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,298,860,435,722, is 1.
Now, the common factors can be found like this.
215:5x 43
298:2x 149
860:2x 2x 5x 43
435:3x 5x 29
722:2x 19x 19
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 5x 43 = 4300
Therefore, the value for common factors is 4300.
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 = 17305319814000/(1x4300)
LCM = 17305319814000/4300
LCM = 4024492980
Thus, we can understand that the LCM of 215,298,860,435,722 is 4024492980.
