Given numbers are 343,630,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 343,630,905 is 5587470.
Find LCM of 343,630,905 with Prime Factorization
| 5 | 343, 630, 905 |
| 7 | 343, 126, 181 |
| 49, 18, 181 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 49 x 18 x 181 = 5587470
Therefore, the lowest common multiple of 343,630,905 is 5587470.
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.
343 x 630 x 905 = 195561450
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.
343 : 1, 7, 49, 343
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,630,905, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
630:2x 3x 3x 5x 7
905:5x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7 = 35
Therefore, the value for common factors is 35.
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 = 195561450/(1x35)
LCM = 195561450/35
LCM = 5587470
Thus, we can understand that the LCM of 343,630,905 is 5587470.
