Find LCM of 781,416,396,213,871 with Prime Factorization
2 | 781, 416, 396, 213, 871 |
2 | 781, 208, 198, 213, 871 |
3 | 781, 104, 99, 213, 871 |
11 | 781, 104, 33, 71, 871 |
13 | 71, 104, 3, 71, 871 |
71 | 71, 8, 3, 71, 67 |
1, 8, 3, 1, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 13 x 71 x 1 x 8 x 3 x 1 x 67 = 195912288
Therefore, the lowest common multiple of 781,416,396,213,871 is 195912288.
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.
781 x 416 x 396 x 213 x 871 = 23869169520768
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.
781 : 1, 11, 71, 781
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
213 : 1, 3, 71, 213
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,416,396,213,871, is 1.
Now, the common factors can be found like this.
781:11x 71
416:2x 2x 2x 2x 2x 13
396:2x 2x 3x 3x 11
213:3x 71
871:13x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 11x 13x 71 = 121836
Therefore, the value for common factors is 121836.
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 = 23869169520768/(1x121836)
LCM = 23869169520768/121836
LCM = 195912288
Thus, we can understand that the LCM of 781,416,396,213,871 is 195912288.
