Given numbers are 247,203,684,491
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,203,684,491 is 886292316.
Find LCM of 247,203,684,491 with Prime Factorization
19 | 247, 203, 684, 491 |
13, 203, 36, 491 |
Multiply the prime numbers at the bottom and the left side.
19 x 13 x 203 x 36 x 491 = 886292316
Therefore, the lowest common multiple of 247,203,684,491 is 886292316.
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.
247 x 203 x 684 x 491 = 16839554004
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.
247 : 1, 13, 19, 247
203 : 1, 7, 29, 203
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
491 : 1, 491
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,203,684,491, is 1.
Now, the common factors can be found like this.
247:13x 19
203:7x 29
684:2x 2x 3x 3x 19
491:491
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 16839554004/(1x19)
LCM = 16839554004/19
LCM = 886292316
Thus, we can understand that the LCM of 247,203,684,491 is 886292316.
