Given numbers are 721,822,210,224,671
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,822,210,224,671 is 31814096160.
Find LCM of 721,822,210,224,671 with Prime Factorization
| 2 | 721, 822, 210, 224, 671 |
| 3 | 721, 411, 105, 112, 671 |
| 7 | 721, 137, 35, 112, 671 |
| 103, 137, 5, 16, 671 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 103 x 137 x 5 x 16 x 671 = 31814096160
Therefore, the lowest common multiple of 721,822,210,224,671 is 31814096160.
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.
721 x 822 x 210 x 224 x 671 = 18706688542080
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.
721 : 1, 7, 103, 721
822 : 1, 2, 3, 6, 137, 274, 411, 822
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
671 : 1, 11, 61, 671
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,822,210,224,671, is 1.
Now, the common factors can be found like this.
721:7x 103
822:2x 3x 137
210:2x 3x 5x 7
224:2x 2x 2x 2x 2x 7
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 3x 7x 7 = 588
Therefore, the value for common factors is 588.
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 = 18706688542080/(1x588)
LCM = 18706688542080/588
LCM = 31814096160
Thus, we can understand that the LCM of 721,822,210,224,671 is 31814096160.
