Given numbers are 422,290,406,145,956
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 422,290,406,145,956 is 204741740.
Find LCM of 422,290,406,145,956 with Prime Factorization
| 2 | 422, 290, 406, 145, 956 |
| 5 | 211, 145, 203, 145, 478 |
| 29 | 211, 29, 203, 29, 478 |
| 211, 1, 7, 1, 478 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 29 x 211 x 1 x 7 x 1 x 478 = 204741740
Therefore, the lowest common multiple of 422,290,406,145,956 is 204741740.
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.
422 x 290 x 406 x 145 x 956 = 6887512133600
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.
422 : 1, 2, 211, 422
290 : 1, 2, 5, 10, 29, 58, 145, 290
406 : 1, 2, 7, 14, 29, 58, 203, 406
145 : 1, 5, 29, 145
956 : 1, 2, 4, 239, 478, 956
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,290,406,145,956, is 1.
Now, the common factors can be found like this.
422:2x 211
290:2x 5x 29
406:2x 7x 29
145:5x 29
956:2x 2x 239
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 5x 29x 29 = 33640
Therefore, the value for common factors is 33640.
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 = 6887512133600/(1x33640)
LCM = 6887512133600/33640
LCM = 204741740
Thus, we can understand that the LCM of 422,290,406,145,956 is 204741740.
