Given numbers are 403,221,340,554
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,221,340,554 is 37954540.
Find LCM of 403,221,340,554 with Prime Factorization
2 | 403, 221, 340, 554 |
13 | 403, 221, 170, 277 |
17 | 31, 17, 170, 277 |
31, 1, 10, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 31 x 1 x 10 x 277 = 37954540
Therefore, the lowest common multiple of 403,221,340,554 is 37954540.
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.
403 x 221 x 340 x 554 = 16775906680
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.
403 : 1, 13, 31, 403
221 : 1, 13, 17, 221
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
554 : 1, 2, 277, 554
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,221,340,554, is 1.
Now, the common factors can be found like this.
403:13x 31
221:13x 17
340:2x 2x 5x 17
554:2x 277
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 17 = 442
Therefore, the value for common factors is 442.
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 = 16775906680/(1x442)
LCM = 16775906680/442
LCM = 37954540
Thus, we can understand that the LCM of 403,221,340,554 is 37954540.
