Given numbers are 429,318,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 429,318,685 is 31149690.
Find LCM of 429,318,685 with Prime Factorization
| 3 | 429, 318, 685 |
| 143, 106, 685 |
Multiply the prime numbers at the bottom and the left side.
3 x 143 x 106 x 685 = 31149690
Therefore, the lowest common multiple of 429,318,685 is 31149690.
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.
429 x 318 x 685 = 93449070
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.
429 : 1, 3, 11, 13, 33, 39, 143, 429
318 : 1, 2, 3, 6, 53, 106, 159, 318
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,318,685, is 1.
Now, the common factors can be found like this.
429:3x 11x 13
318:2x 3x 53
685:5x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 93449070/(1x3)
LCM = 93449070/3
LCM = 31149690
Thus, we can understand that the LCM of 429,318,685 is 31149690.
