Given numbers are 109,246,749,441
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 109,246,749,441 is 421757406.
Find LCM of 109,246,749,441 with Prime Factorization
| 3 | 109, 246, 749, 441 |
| 7 | 109, 82, 749, 147 |
| 109, 82, 107, 21 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 109 x 82 x 107 x 21 = 421757406
Therefore, the lowest common multiple of 109,246,749,441 is 421757406.
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.
109 x 246 x 749 x 441 = 8856905526
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.
109 : 1, 109
246 : 1, 2, 3, 6, 41, 82, 123, 246
749 : 1, 7, 107, 749
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 109,246,749,441, is 1.
Now, the common factors can be found like this.
109:109
246:2x 3x 41
749:7x 107
441:3x 3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 8856905526/(1x21)
LCM = 8856905526/21
LCM = 421757406
Thus, we can understand that the LCM of 109,246,749,441 is 421757406.
