Find LCM of 347,280,920,427,671 with Prime Factorization
| 2 | 347, 280, 920, 427, 671 |
| 2 | 347, 140, 460, 427, 671 |
| 2 | 347, 70, 230, 427, 671 |
| 5 | 347, 35, 115, 427, 671 |
| 7 | 347, 7, 23, 427, 671 |
| 61 | 347, 1, 23, 61, 671 |
| 347, 1, 23, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 61 x 347 x 1 x 23 x 1 x 11 = 1499470280
Therefore, the lowest common multiple of 347,280,920,427,671 is 1499470280.
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.
347 x 280 x 920 x 427 x 671 = 25610952382400
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.
347 : 1, 347
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
427 : 1, 7, 61, 427
671 : 1, 11, 61, 671
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,280,920,427,671, is 1.
Now, the common factors can be found like this.
347:347
280:2x 2x 2x 5x 7
920:2x 2x 2x 5x 23
427:7x 61
671:11x 61
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 5x 7x 61 = 17080
Therefore, the value for common factors is 17080.
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 = 25610952382400/(1x17080)
LCM = 25610952382400/17080
LCM = 1499470280
Thus, we can understand that the LCM of 347,280,920,427,671 is 1499470280.
