Given numbers are 638,410,126,224,109
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,410,126,224,109 is 14370158880.
Find LCM of 638,410,126,224,109 with Prime Factorization
| 2 | 638, 410, 126, 224, 109 |
| 7 | 319, 205, 63, 112, 109 |
| 319, 205, 9, 16, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 319 x 205 x 9 x 16 x 109 = 14370158880
Therefore, the lowest common multiple of 638,410,126,224,109 is 14370158880.
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.
638 x 410 x 126 x 224 x 109 = 804728897280
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
410 : 1, 2, 5, 10, 41, 82, 205, 410
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
109 : 1, 109
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,410,126,224,109, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
410:2x 5x 41
126:2x 3x 3x 7
224:2x 2x 2x 2x 2x 7
109:109
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 2x 7 = 56
Therefore, the value for common factors is 56.
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 = 804728897280/(1x56)
LCM = 804728897280/56
LCM = 14370158880
Thus, we can understand that the LCM of 638,410,126,224,109 is 14370158880.
