Find LCM of 630,791,344,301,819 with Prime Factorization
| 2 | 630, 791, 344, 301, 819 |
| 3 | 315, 791, 172, 301, 819 |
| 3 | 105, 791, 172, 301, 273 |
| 7 | 35, 791, 172, 301, 91 |
| 43 | 5, 113, 172, 43, 13 |
| 5, 113, 4, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 43 x 5 x 113 x 4 x 1 x 13 = 159180840
Therefore, the lowest common multiple of 630,791,344,301,819 is 159180840.
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.
630 x 791 x 344 x 301 x 819 = 42259647764880
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
791 : 1, 7, 113, 791
344 : 1, 2, 4, 8, 43, 86, 172, 344
301 : 1, 7, 43, 301
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,791,344,301,819, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
791:7x 113
344:2x 2x 2x 43
301:7x 43
819:3x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7x 7x 7x 43 = 265482
Therefore, the value for common factors is 265482.
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 = 42259647764880/(1x265482)
LCM = 42259647764880/265482
LCM = 159180840
Thus, we can understand that the LCM of 630,791,344,301,819 is 159180840.
