Find LCM of 920,176,709,814,221 with Prime Factorization
| 2 | 920, 176, 709, 814, 221 |
| 2 | 460, 88, 709, 407, 221 |
| 2 | 230, 44, 709, 407, 221 |
| 11 | 115, 22, 709, 407, 221 |
| 115, 2, 709, 37, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 115 x 2 x 709 x 37 x 221 = 117341258320
Therefore, the lowest common multiple of 920,176,709,814,221 is 117341258320.
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.
920 x 176 x 709 x 814 x 221 = 20652061464320
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
709 : 1, 709
814 : 1, 2, 11, 22, 37, 74, 407, 814
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,176,709,814,221, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
176:2x 2x 2x 2x 11
709:709
814:2x 11x 37
221:13x 17
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 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 20652061464320/(1x176)
LCM = 20652061464320/176
LCM = 117341258320
Thus, we can understand that the LCM of 920,176,709,814,221 is 117341258320.
