The LCM of 671,420,221,928,176 is 14449475040.
Find LCM of 671,420,221,928,176 with Prime Factorization
| 2 | 671, 420, 221, 928, 176 |
| 2 | 671, 210, 221, 464, 88 |
| 2 | 671, 105, 221, 232, 44 |
| 2 | 671, 105, 221, 116, 22 |
| 11 | 671, 105, 221, 58, 11 |
| 61, 105, 221, 58, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 11 x 61 x 105 x 221 x 58 x 1 = 14449475040
Therefore, the lowest common multiple of 671,420,221,928,176 is 14449475040.
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.
671 x 420 x 221 x 928 x 176 = 10172430428160
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.
671 : 1, 11, 61, 671
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
221 : 1, 13, 17, 221
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,420,221,928,176, is 1.
Now, the common factors can be found like this.
671:11x 61
420:2x 2x 3x 5x 7
221:13x 17
928:2x 2x 2x 2x 2x 29
176:2x 2x 2x 2x 11
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 2x 2x 11 = 704
Therefore, the value for common factors is 704.
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 = 10172430428160/(1x704)
LCM = 10172430428160/704
LCM = 14449475040
Thus, we can understand that the LCM of 671,420,221,928,176 is 14449475040.
