Find LCM of 345,384,680,697,626 with Prime Factorization
| 2 | 345, 384, 680, 697, 626 |
| 2 | 345, 192, 340, 697, 313 |
| 2 | 345, 96, 170, 697, 313 |
| 3 | 345, 48, 85, 697, 313 |
| 5 | 115, 16, 85, 697, 313 |
| 17 | 23, 16, 17, 697, 313 |
| 23, 16, 1, 41, 313 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 17 x 23 x 16 x 1 x 41 x 313 = 9633989760
Therefore, the lowest common multiple of 345,384,680,697,626 is 9633989760.
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.
345 x 384 x 680 x 697 x 626 = 39306678220800
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.
345 : 1, 3, 5, 15, 23, 69, 115, 345
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
697 : 1, 17, 41, 697
626 : 1, 2, 313, 626
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,384,680,697,626, is 1.
Now, the common factors can be found like this.
345:3x 5x 23
384:2x 2x 2x 2x 2x 2x 2x 3
680:2x 2x 2x 5x 17
697:17x 41
626:2x 313
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 2x 2x 3x 5x 17 = 4080
Therefore, the value for common factors is 4080.
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 = 39306678220800/(1x4080)
LCM = 39306678220800/4080
LCM = 9633989760
Thus, we can understand that the LCM of 345,384,680,697,626 is 9633989760.
