Given numbers are 662,642,466,499,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 662,642,466,499,749 is 172948790238.
Find LCM of 662,642,466,499,749 with Prime Factorization
| 2 | 662, 642, 466, 499, 749 |
| 107 | 331, 321, 233, 499, 749 |
| 331, 3, 233, 499, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 107 x 331 x 3 x 233 x 499 x 7 = 172948790238
Therefore, the lowest common multiple of 662,642,466,499,749 is 172948790238.
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.
662 x 642 x 466 x 499 x 749 = 74022082221864
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.
662 : 1, 2, 331, 662
642 : 1, 2, 3, 6, 107, 214, 321, 642
466 : 1, 2, 233, 466
499 : 1, 499
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,642,466,499,749, is 1.
Now, the common factors can be found like this.
662:2x 331
642:2x 3x 107
466:2x 233
499:499
749:7x 107
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 107 = 428
Therefore, the value for common factors is 428.
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 = 74022082221864/(1x428)
LCM = 74022082221864/428
LCM = 172948790238
Thus, we can understand that the LCM of 662,642,466,499,749 is 172948790238.
