Find LCM of 665,880,420,880,473 with Prime Factorization
| 2 | 665, 880, 420, 880, 473 |
| 2 | 665, 440, 210, 440, 473 |
| 2 | 665, 220, 105, 220, 473 |
| 2 | 665, 110, 105, 110, 473 |
| 5 | 665, 55, 105, 55, 473 |
| 7 | 133, 11, 21, 11, 473 |
| 11 | 19, 11, 3, 11, 473 |
| 19, 1, 3, 1, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 7 x 11 x 19 x 1 x 3 x 1 x 43 = 15098160
Therefore, the lowest common multiple of 665,880,420,880,473 is 15098160.
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.
665 x 880 x 420 x 880 x 473 = 102305132160000
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
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
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
473 : 1, 11, 43, 473
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,880,420,880,473, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
880:2x 2x 2x 2x 5x 11
420:2x 2x 3x 5x 7
880:2x 2x 2x 2x 5x 11
473:11x 43
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 5x 5x 5x 7x 11x 11 = 6776000
Therefore, the value for common factors is 6776000.
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 = 102305132160000/(1x6776000)
LCM = 102305132160000/6776000
LCM = 15098160
Thus, we can understand that the LCM of 665,880,420,880,473 is 15098160.
