Given numbers are 162,501,399,398
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 162,501,399,398 is 716038218.
Find LCM of 162,501,399,398 with Prime Factorization
| 2 | 162, 501, 399, 398 |
| 3 | 81, 501, 399, 199 |
| 27, 167, 133, 199 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 27 x 167 x 133 x 199 = 716038218
Therefore, the lowest common multiple of 162,501,399,398 is 716038218.
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.
162 x 501 x 399 x 398 = 12888687924
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.
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
501 : 1, 3, 167, 501
399 : 1, 3, 7, 19, 21, 57, 133, 399
398 : 1, 2, 199, 398
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 162,501,399,398, is 1.
Now, the common factors can be found like this.
162:2x 3x 3x 3x 3
501:3x 167
399:3x 7x 19
398:2x 199
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 3 = 18
Therefore, the value for common factors is 18.
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 = 12888687924/(1x18)
LCM = 12888687924/18
LCM = 716038218
Thus, we can understand that the LCM of 162,501,399,398 is 716038218.
