The LCM of 847,785,736,730,621 is 964533921120.
Find LCM of 847,785,736,730,621 with Prime Factorization
| 2 | 847, 785, 736, 730, 621 |
| 5 | 847, 785, 368, 365, 621 |
| 23 | 847, 157, 368, 73, 621 |
| 847, 157, 16, 73, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 847 x 157 x 16 x 73 x 27 = 964533921120
Therefore, the lowest common multiple of 847,785,736,730,621 is 964533921120.
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.
847 x 785 x 736 x 730 x 621 = 221842801857600
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.
847 : 1, 7, 11, 77, 121, 847
785 : 1, 5, 157, 785
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
730 : 1, 2, 5, 10, 73, 146, 365, 730
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,785,736,730,621, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
785:5x 157
736:2x 2x 2x 2x 2x 23
730:2x 5x 73
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 23 = 230
Therefore, the value for common factors is 230.
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 = 221842801857600/(1x230)
LCM = 221842801857600/230
LCM = 964533921120
Thus, we can understand that the LCM of 847,785,736,730,621 is 964533921120.
