Given numbers are 987,572,143,447
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,572,143,447 is 84120036.
Find LCM of 987,572,143,447 with Prime Factorization
| 3 | 987, 572, 143, 447 |
| 11 | 329, 572, 143, 149 |
| 13 | 329, 52, 13, 149 |
| 329, 4, 1, 149 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 13 x 329 x 4 x 1 x 149 = 84120036
Therefore, the lowest common multiple of 987,572,143,447 is 84120036.
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.
987 x 572 x 143 x 447 = 36087495444
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
143 : 1, 11, 13, 143
447 : 1, 3, 149, 447
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,572,143,447, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
572:2x 2x 11x 13
143:11x 13
447:3x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 13 = 429
Therefore, the value for common factors is 429.
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 = 36087495444/(1x429)
LCM = 36087495444/429
LCM = 84120036
Thus, we can understand that the LCM of 987,572,143,447 is 84120036.
