Find LCM of 785,628,939,560,729 with Prime Factorization
2 | 785, 628, 939, 560, 729 |
2 | 785, 314, 939, 280, 729 |
3 | 785, 157, 939, 140, 729 |
5 | 785, 157, 313, 140, 243 |
157 | 157, 157, 313, 28, 243 |
1, 1, 313, 28, 243 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 157 x 1 x 1 x 313 x 28 x 243 = 20061321840
Therefore, the lowest common multiple of 785,628,939,560,729 is 20061321840.
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.
785 x 628 x 939 x 560 x 729 = 188977651732800
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.
785 : 1, 5, 157, 785
628 : 1, 2, 4, 157, 314, 628
939 : 1, 3, 313, 939
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
729 : 1, 3, 9, 27, 81, 243, 729
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,628,939,560,729, is 1.
Now, the common factors can be found like this.
785:5x 157
628:2x 2x 157
939:3x 313
560:2x 2x 2x 2x 5x 7
729:3x 3x 3x 3x 3x 3
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 3x 5x 157 = 9420
Therefore, the value for common factors is 9420.
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 = 188977651732800/(1x9420)
LCM = 188977651732800/9420
LCM = 20061321840
Thus, we can understand that the LCM of 785,628,939,560,729 is 20061321840.
