Find LCM of 660,529,595,758,721 with Prime Factorization
| 2 | 660, 529, 595, 758, 721 |
| 5 | 330, 529, 595, 379, 721 |
| 7 | 66, 529, 119, 379, 721 |
| 66, 529, 17, 379, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 66 x 529 x 17 x 379 x 103 = 1621896003420
Therefore, the lowest common multiple of 660,529,595,758,721 is 1621896003420.
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.
660 x 529 x 595 x 758 x 721 = 113532720239400
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.
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
529 : 1, 23, 529
595 : 1, 5, 7, 17, 35, 85, 119, 595
758 : 1, 2, 379, 758
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,529,595,758,721, is 1.
Now, the common factors can be found like this.
660:2x 2x 3x 5x 11
529:23x 23
595:5x 7x 17
758:2x 379
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 5x 7 = 70
Therefore, the value for common factors is 70.
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 = 113532720239400/(1x70)
LCM = 113532720239400/70
LCM = 1621896003420
Thus, we can understand that the LCM of 660,529,595,758,721 is 1621896003420.
