Find LCM of 315,143,861,711,841 with Prime Factorization
3 | 315, 143, 861, 711, 841 |
3 | 105, 143, 287, 237, 841 |
7 | 35, 143, 287, 79, 841 |
5, 143, 41, 79, 841 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 5 x 143 x 41 x 79 x 841 = 122702534955
Therefore, the lowest common multiple of 315,143,861,711,841 is 122702534955.
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.
315 x 143 x 861 x 711 x 841 = 23190779106495
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
143 : 1, 11, 13, 143
861 : 1, 3, 7, 21, 41, 123, 287, 861
711 : 1, 3, 9, 79, 237, 711
841 : 1, 29, 841
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,143,861,711,841, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
143:11x 13
861:3x 7x 41
711:3x 3x 79
841:29x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7 = 189
Therefore, the value for common factors is 189.
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 = 23190779106495/(1x189)
LCM = 23190779106495/189
LCM = 122702534955
Thus, we can understand that the LCM of 315,143,861,711,841 is 122702534955.
