Given numbers are 669,381,360,414,298
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,381,360,414,298 is 34940184120.
Find LCM of 669,381,360,414,298 with Prime Factorization
| 2 | 669, 381, 360, 414, 298 |
| 3 | 669, 381, 180, 207, 149 |
| 3 | 223, 127, 60, 69, 149 |
| 223, 127, 20, 23, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 223 x 127 x 20 x 23 x 149 = 34940184120
Therefore, the lowest common multiple of 669,381,360,414,298 is 34940184120.
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.
669 x 381 x 360 x 414 x 298 = 11320619654880
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.
669 : 1, 3, 223, 669
381 : 1, 3, 127, 381
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
298 : 1, 2, 149, 298
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,381,360,414,298, is 1.
Now, the common factors can be found like this.
669:3x 223
381:3x 127
360:2x 2x 2x 3x 3x 5
414:2x 3x 3x 23
298:2x 149
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 3x 3x 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 11320619654880/(1x324)
LCM = 11320619654880/324
LCM = 34940184120
Thus, we can understand that the LCM of 669,381,360,414,298 is 34940184120.
