Given numbers are 955,403,320,434
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 955,403,320,434 is 172419520.
Find LCM of 955,403,320,434 with Prime Factorization
| 2 | 955, 403, 320, 434 |
| 5 | 955, 403, 160, 217 |
| 31 | 191, 403, 32, 217 |
| 191, 13, 32, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 31 x 191 x 13 x 32 x 7 = 172419520
Therefore, the lowest common multiple of 955,403,320,434 is 172419520.
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.
955 x 403 x 320 x 434 = 53450051200
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.
955 : 1, 5, 191, 955
403 : 1, 13, 31, 403
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
434 : 1, 2, 7, 14, 31, 62, 217, 434
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 955,403,320,434, is 1.
Now, the common factors can be found like this.
955:5x 191
403:13x 31
320:2x 2x 2x 2x 2x 2x 5
434:2x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 31 = 310
Therefore, the value for common factors is 310.
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 = 53450051200/(1x310)
LCM = 53450051200/310
LCM = 172419520
Thus, we can understand that the LCM of 955,403,320,434 is 172419520.
