Given numbers are 676,300,812,917,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,300,812,917,643 is 866934459300.
Find LCM of 676,300,812,917,643 with Prime Factorization
| 2 | 676, 300, 812, 917, 643 |
| 2 | 338, 150, 406, 917, 643 |
| 7 | 169, 75, 203, 917, 643 |
| 169, 75, 29, 131, 643 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 169 x 75 x 29 x 131 x 643 = 866934459300
Therefore, the lowest common multiple of 676,300,812,917,643 is 866934459300.
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.
676 x 300 x 812 x 917 x 643 = 97096659441600
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
917 : 1, 7, 131, 917
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,300,812,917,643, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
300:2x 2x 3x 5x 5
812:2x 2x 7x 29
917:7x 131
643:643
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 7 = 112
Therefore, the value for common factors is 112.
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 = 97096659441600/(1x112)
LCM = 97096659441600/112
LCM = 866934459300
Thus, we can understand that the LCM of 676,300,812,917,643 is 866934459300.
