Find LCM of 171,156,728,826,397 with Prime Factorization
| 2 | 171, 156, 728, 826, 397 |
| 2 | 171, 78, 364, 413, 397 |
| 3 | 171, 39, 182, 413, 397 |
| 7 | 57, 13, 182, 413, 397 |
| 13 | 57, 13, 26, 59, 397 |
| 57, 1, 2, 59, 397 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 13 x 57 x 1 x 2 x 59 x 397 = 2915882424
Therefore, the lowest common multiple of 171,156,728,826,397 is 2915882424.
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.
171 x 156 x 728 x 826 x 397 = 6368287214016
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.
171 : 1, 3, 9, 19, 57, 171
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
826 : 1, 2, 7, 14, 59, 118, 413, 826
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,156,728,826,397, is 1.
Now, the common factors can be found like this.
171:3x 3x 19
156:2x 2x 3x 13
728:2x 2x 2x 7x 13
826:2x 7x 59
397:397
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 2x 3x 7x 13 = 2184
Therefore, the value for common factors is 2184.
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 = 6368287214016/(1x2184)
LCM = 6368287214016/2184
LCM = 2915882424
Thus, we can understand that the LCM of 171,156,728,826,397 is 2915882424.
