Given numbers are 677,588,766,674,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 677,588,766,674,721 is 5292146941788.
Find LCM of 677,588,766,674,721 with Prime Factorization
| 2 | 677, 588, 766, 674, 721 |
| 7 | 677, 294, 383, 337, 721 |
| 677, 42, 383, 337, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 677 x 42 x 383 x 337 x 103 = 5292146941788
Therefore, the lowest common multiple of 677,588,766,674,721 is 5292146941788.
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.
677 x 588 x 766 x 674 x 721 = 148180114370064
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.
677 : 1, 677
588 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 49, 84, 98, 147, 196, 294, 588
766 : 1, 2, 383, 766
674 : 1, 2, 337, 674
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 677,588,766,674,721, is 1.
Now, the common factors can be found like this.
677:677
588:2x 2x 3x 7x 7
766:2x 383
674:2x 337
721:7x 103
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 7 = 28
Therefore, the value for common factors is 28.
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 = 148180114370064/(1x28)
LCM = 148180114370064/28
LCM = 5292146941788
Thus, we can understand that the LCM of 677,588,766,674,721 is 5292146941788.
