The LCM of 161,588,778,621 is 47347524.
Find LCM of 161,588,778,621 with Prime Factorization
| 2 | 161, 588, 778, 621 |
| 3 | 161, 294, 389, 621 |
| 7 | 161, 98, 389, 207 |
| 23 | 23, 14, 389, 207 |
| 1, 14, 389, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 1 x 14 x 389 x 9 = 47347524
Therefore, the lowest common multiple of 161,588,778,621 is 47347524.
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.
161 x 588 x 778 x 621 = 45737708184
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.
161 : 1, 7, 23, 161
588 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 49, 84, 98, 147, 196, 294, 588
778 : 1, 2, 389, 778
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 161,588,778,621, is 1.
Now, the common factors can be found like this.
161:7x 23
588:2x 2x 3x 7x 7
778:2x 389
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 3x 7x 23 = 966
Therefore, the value for common factors is 966.
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 = 45737708184/(1x966)
LCM = 45737708184/966
LCM = 47347524
Thus, we can understand that the LCM of 161,588,778,621 is 47347524.
