Given numbers are 429,661,688,258
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 429,661,688,258 is 195095472.
Find LCM of 429,661,688,258 with Prime Factorization
| 2 | 429, 661, 688, 258 |
| 3 | 429, 661, 344, 129 |
| 43 | 143, 661, 344, 43 |
| 143, 661, 8, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 43 x 143 x 661 x 8 x 1 = 195095472
Therefore, the lowest common multiple of 429,661,688,258 is 195095472.
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 661 x 688 x 258 = 50334631776
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
661 : 1, 661
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
258 : 1, 2, 3, 6, 43, 86, 129, 258
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,661,688,258, is 1.
Now, the common factors can be found like this.
429:3x 11x 13
661:661
688:2x 2x 2x 2x 43
258:2x 3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 43 = 258
Therefore, the value for common factors is 258.
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 = 50334631776/(1x258)
LCM = 50334631776/258
LCM = 195095472
Thus, we can understand that the LCM of 429,661,688,258 is 195095472.
