Given numbers are 429,63,869,917
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 429,63,869,917 is 93234141.
Find LCM of 429,63,869,917 with Prime Factorization
| 3 | 429, 63, 869, 917 |
| 7 | 143, 21, 869, 917 |
| 11 | 143, 3, 869, 131 |
| 13, 3, 79, 131 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 13 x 3 x 79 x 131 = 93234141
Therefore, the lowest common multiple of 429,63,869,917 is 93234141.
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 63 x 869 x 917 = 21537086571
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
63 : 1, 3, 7, 9, 21, 63
869 : 1, 11, 79, 869
917 : 1, 7, 131, 917
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,63,869,917, is 1.
Now, the common factors can be found like this.
429:3x 11x 13
63:3x 3x 7
869:11x 79
917:7x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 11 = 231
Therefore, the value for common factors is 231.
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 = 21537086571/(1x231)
LCM = 21537086571/231
LCM = 93234141
Thus, we can understand that the LCM of 429,63,869,917 is 93234141.
