Find LCM of 784,699,432,809,681 with Prime Factorization
| 2 | 784, 699, 432, 809, 681 |
| 2 | 392, 699, 216, 809, 681 |
| 2 | 196, 699, 108, 809, 681 |
| 2 | 98, 699, 54, 809, 681 |
| 3 | 49, 699, 27, 809, 681 |
| 49, 233, 9, 809, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 49 x 233 x 9 x 809 x 227 = 905753720592
Therefore, the lowest common multiple of 784,699,432,809,681 is 905753720592.
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.
784 x 699 x 432 x 809 x 681 = 130428535765248
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
699 : 1, 3, 233, 699
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
809 : 1, 809
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,699,432,809,681, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
699:3x 233
432:2x 2x 2x 2x 3x 3x 3
809:809
681:3x 227
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 3 = 144
Therefore, the value for common factors is 144.
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 = 130428535765248/(1x144)
LCM = 130428535765248/144
LCM = 905753720592
Thus, we can understand that the LCM of 784,699,432,809,681 is 905753720592.
