Given numbers are 108,572,403,42
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 108,572,403,42 is 3351348.
Find LCM of 108,572,403,42 with Prime Factorization
| 2 | 108, 572, 403, 42 |
| 2 | 54, 286, 403, 21 |
| 3 | 27, 143, 403, 21 |
| 13 | 9, 143, 403, 7 |
| 9, 11, 31, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 9 x 11 x 31 x 7 = 3351348
Therefore, the lowest common multiple of 108,572,403,42 is 3351348.
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.
108 x 572 x 403 x 42 = 1045620576
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.
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
403 : 1, 13, 31, 403
42 : 1, 2, 3, 6, 7, 14, 21, 42
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 108,572,403,42, is 1.
Now, the common factors can be found like this.
108:2x 2x 3x 3x 3
572:2x 2x 11x 13
403:13x 31
42:2x 3x 7
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 3x 13 = 312
Therefore, the value for common factors is 312.
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 = 1045620576/(1x312)
LCM = 1045620576/312
LCM = 3351348
Thus, we can understand that the LCM of 108,572,403,42 is 3351348.
