Given numbers are 399,724,164,822
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,724,164,822 is 1622616492.
Find LCM of 399,724,164,822 with Prime Factorization
| 2 | 399, 724, 164, 822 |
| 2 | 399, 362, 82, 411 |
| 3 | 399, 181, 41, 411 |
| 133, 181, 41, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 133 x 181 x 41 x 137 = 1622616492
Therefore, the lowest common multiple of 399,724,164,822 is 1622616492.
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.
399 x 724 x 164 x 822 = 38942795808
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
724 : 1, 2, 4, 181, 362, 724
164 : 1, 2, 4, 41, 82, 164
822 : 1, 2, 3, 6, 137, 274, 411, 822
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,724,164,822, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
724:2x 2x 181
164:2x 2x 41
822:2x 3x 137
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 3 = 24
Therefore, the value for common factors is 24.
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 = 38942795808/(1x24)
LCM = 38942795808/24
LCM = 1622616492
Thus, we can understand that the LCM of 399,724,164,822 is 1622616492.
