Given numbers are 431,161,540,714,322
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 431,161,540,714,322 is 637009380.
Find LCM of 431,161,540,714,322 with Prime Factorization
| 2 | 431, 161, 540, 714, 322 |
| 3 | 431, 161, 270, 357, 161 |
| 7 | 431, 161, 90, 119, 161 |
| 23 | 431, 23, 90, 17, 23 |
| 431, 1, 90, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 431 x 1 x 90 x 17 x 1 = 637009380
Therefore, the lowest common multiple of 431,161,540,714,322 is 637009380.
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.
431 x 161 x 540 x 714 x 322 = 8614914855120
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.
431 : 1, 431
161 : 1, 7, 23, 161
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
322 : 1, 2, 7, 14, 23, 46, 161, 322
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,161,540,714,322, is 1.
Now, the common factors can be found like this.
431:431
161:7x 23
540:2x 2x 3x 3x 3x 5
714:2x 3x 7x 17
322:2x 7x 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 2x 3x 7x 7x 23 = 13524
Therefore, the value for common factors is 13524.
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 = 8614914855120/(1x13524)
LCM = 8614914855120/13524
LCM = 637009380
Thus, we can understand that the LCM of 431,161,540,714,322 is 637009380.
