Find LCM of 520,346,680,643,801 with Prime Factorization
| 2 | 520, 346, 680, 643, 801 |
| 2 | 260, 173, 340, 643, 801 |
| 2 | 130, 173, 170, 643, 801 |
| 5 | 65, 173, 85, 643, 801 |
| 13, 173, 17, 643, 801 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 13 x 173 x 17 x 643 x 801 = 787665560760
Therefore, the lowest common multiple of 520,346,680,643,801 is 787665560760.
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.
520 x 346 x 680 x 643 x 801 = 63013244860800
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.
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
346 : 1, 2, 173, 346
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
643 : 1, 643
801 : 1, 3, 9, 89, 267, 801
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,346,680,643,801, is 1.
Now, the common factors can be found like this.
520:2x 2x 2x 5x 13
346:2x 173
680:2x 2x 2x 5x 17
643:643
801:3x 3x 89
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 5 = 80
Therefore, the value for common factors is 80.
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 = 63013244860800/(1x80)
LCM = 63013244860800/80
LCM = 787665560760
Thus, we can understand that the LCM of 520,346,680,643,801 is 787665560760.
