Given numbers are 755,311,355,636,421
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 755,311,355,636,421 is 4463801778180.
Find LCM of 755,311,355,636,421 with Prime Factorization
5 | 755, 311, 355, 636, 421 |
151, 311, 71, 636, 421 |
Multiply the prime numbers at the bottom and the left side.
5 x 151 x 311 x 71 x 636 x 421 = 4463801778180
Therefore, the lowest common multiple of 755,311,355,636,421 is 4463801778180.
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.
755 x 311 x 355 x 636 x 421 = 22319008890900
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.
755 : 1, 5, 151, 755
311 : 1, 311
355 : 1, 5, 71, 355
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 755,311,355,636,421, is 1.
Now, the common factors can be found like this.
755:5x 151
311:311
355:5x 71
636:2x 2x 3x 53
421:421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 22319008890900/(1x5)
LCM = 22319008890900/5
LCM = 4463801778180
Thus, we can understand that the LCM of 755,311,355,636,421 is 4463801778180.
