Find LCM of 856,747,507,715,165 with Prime Factorization
| 3 | 856, 747, 507, 715, 165 |
| 5 | 856, 249, 169, 715, 55 |
| 11 | 856, 249, 169, 143, 11 |
| 13 | 856, 249, 169, 13, 1 |
| 856, 249, 1, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 13 x 856 x 249 x 1 x 13 x 1 = 5943520440
Therefore, the lowest common multiple of 856,747,507,715,165 is 5943520440.
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.
856 x 747 x 507 x 715 x 165 = 38246554031400
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
747 : 1, 3, 9, 83, 249, 747
507 : 1, 3, 13, 39, 169, 507
715 : 1, 5, 11, 13, 55, 65, 143, 715
165 : 1, 3, 5, 11, 15, 33, 55, 165
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,747,507,715,165, is 1.
Now, the common factors can be found like this.
856:2x 2x 2x 107
747:3x 3x 83
507:3x 13x 13
715:5x 11x 13
165:3x 5x 11
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 5x 11x 13 = 6435
Therefore, the value for common factors is 6435.
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 = 38246554031400/(1x6435)
LCM = 38246554031400/6435
LCM = 5943520440
Thus, we can understand that the LCM of 856,747,507,715,165 is 5943520440.
