Find LCM of 343,962,910,630,391 with Prime Factorization
| 2 | 343, 962, 910, 630, 391 |
| 5 | 343, 481, 455, 315, 391 |
| 7 | 343, 481, 91, 63, 391 |
| 13 | 49, 481, 13, 9, 391 |
| 49, 37, 1, 9, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 13 x 49 x 37 x 1 x 9 x 391 = 5805751770
Therefore, the lowest common multiple of 343,962,910,630,391 is 5805751770.
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.
343 x 962 x 910 x 630 x 391 = 73965277549800
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.
343 : 1, 7, 49, 343
962 : 1, 2, 13, 26, 37, 74, 481, 962
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
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
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,962,910,630,391, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
962:2x 13x 37
910:2x 5x 7x 13
630:2x 3x 3x 5x 7
391:17x 23
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 5x 7x 7x 13 = 12740
Therefore, the value for common factors is 12740.
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 = 73965277549800/(1x12740)
LCM = 73965277549800/12740
LCM = 5805751770
Thus, we can understand that the LCM of 343,962,910,630,391 is 5805751770.
