The LCM of 804,635,954,634,640 is 823447923840.
Find LCM of 804,635,954,634,640 with Prime Factorization
| 2 | 804, 635, 954, 634, 640 |
| 2 | 402, 635, 477, 317, 320 |
| 3 | 201, 635, 477, 317, 160 |
| 5 | 67, 635, 159, 317, 160 |
| 67, 127, 159, 317, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 67 x 127 x 159 x 317 x 32 = 823447923840
Therefore, the lowest common multiple of 804,635,954,634,640 is 823447923840.
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.
804 x 635 x 954 x 634 x 640 = 197627501721600
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.
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
635 : 1, 5, 127, 635
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
634 : 1, 2, 317, 634
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 804,635,954,634,640, is 1.
Now, the common factors can be found like this.
804:2x 2x 3x 67
635:5x 127
954:2x 3x 3x 53
634:2x 317
640:2x 2x 2x 2x 2x 2x 2x 5
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 5 = 240
Therefore, the value for common factors is 240.
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 = 197627501721600/(1x240)
LCM = 197627501721600/240
LCM = 823447923840
Thus, we can understand that the LCM of 804,635,954,634,640 is 823447923840.
