The LCM of 708,834,161,621 is 142598988.
Find LCM of 708,834,161,621 with Prime Factorization
| 2 | 708, 834, 161, 621 |
| 3 | 354, 417, 161, 621 |
| 23 | 118, 139, 161, 207 |
| 118, 139, 7, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 118 x 139 x 7 x 9 = 142598988
Therefore, the lowest common multiple of 708,834,161,621 is 142598988.
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.
708 x 834 x 161 x 621 = 59035981032
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.
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
834 : 1, 2, 3, 6, 139, 278, 417, 834
161 : 1, 7, 23, 161
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 708,834,161,621, is 1.
Now, the common factors can be found like this.
708:2x 2x 3x 59
834:2x 3x 139
161:7x 23
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 3x 23 = 414
Therefore, the value for common factors is 414.
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 = 59035981032/(1x414)
LCM = 59035981032/414
LCM = 142598988
Thus, we can understand that the LCM of 708,834,161,621 is 142598988.
