Find LCM of 649,839,355,424,400 with Prime Factorization
| 2 | 649, 839, 355, 424, 400 |
| 2 | 649, 839, 355, 212, 200 |
| 2 | 649, 839, 355, 106, 100 |
| 5 | 649, 839, 355, 53, 50 |
| 649, 839, 71, 53, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 649 x 839 x 71 x 53 x 10 = 819597957200
Therefore, the lowest common multiple of 649,839,355,424,400 is 819597957200.
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.
649 x 839 x 355 x 424 x 400 = 32783918288000
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.
649 : 1, 11, 59, 649
839 : 1, 839
355 : 1, 5, 71, 355
424 : 1, 2, 4, 8, 53, 106, 212, 424
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,839,355,424,400, is 1.
Now, the common factors can be found like this.
649:11x 59
839:839
355:5x 71
424:2x 2x 2x 53
400:2x 2x 2x 2x 5x 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 5 = 40
Therefore, the value for common factors is 40.
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 = 32783918288000/(1x40)
LCM = 32783918288000/40
LCM = 819597957200
Thus, we can understand that the LCM of 649,839,355,424,400 is 819597957200.
