Given numbers are 355,214,535,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 355,214,535,638 is 24234430.
Find LCM of 355,214,535,638 with Prime Factorization
| 2 | 355, 214, 535, 638 |
| 5 | 355, 107, 535, 319 |
| 107 | 71, 107, 107, 319 |
| 71, 1, 1, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 107 x 71 x 1 x 1 x 319 = 24234430
Therefore, the lowest common multiple of 355,214,535,638 is 24234430.
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.
355 x 214 x 535 x 638 = 25930840100
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.
355 : 1, 5, 71, 355
214 : 1, 2, 107, 214
535 : 1, 5, 107, 535
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,214,535,638, is 1.
Now, the common factors can be found like this.
355:5x 71
214:2x 107
535:5x 107
638:2x 11x 29
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 107 = 1070
Therefore, the value for common factors is 1070.
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 = 25930840100/(1x1070)
LCM = 25930840100/1070
LCM = 24234430
Thus, we can understand that the LCM of 355,214,535,638 is 24234430.
