Given numbers are 676,800,781,847
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,800,781,847 is 8130522400.
Find LCM of 676,800,781,847 with Prime Factorization
| 2 | 676, 800, 781, 847 |
| 2 | 338, 400, 781, 847 |
| 11 | 169, 200, 781, 847 |
| 169, 200, 71, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 169 x 200 x 71 x 77 = 8130522400
Therefore, the lowest common multiple of 676,800,781,847 is 8130522400.
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 800 x 781 x 847 = 357742985600
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
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
781 : 1, 11, 71, 781
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,800,781,847, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
800:2x 2x 2x 2x 2x 5x 5
781:11x 71
847:7x 11x 11
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 11 = 44
Therefore, the value for common factors is 44.
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 = 357742985600/(1x44)
LCM = 357742985600/44
LCM = 8130522400
Thus, we can understand that the LCM of 676,800,781,847 is 8130522400.
