Given numbers are 418,244,355,976
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,244,355,976 is 72414320.
Find LCM of 418,244,355,976 with Prime Factorization
2 | 418, 244, 355, 976 |
2 | 209, 122, 355, 488 |
61 | 209, 61, 355, 244 |
209, 1, 355, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 61 x 209 x 1 x 355 x 4 = 72414320
Therefore, the lowest common multiple of 418,244,355,976 is 72414320.
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.
418 x 244 x 355 x 976 = 35338188160
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
244 : 1, 2, 4, 61, 122, 244
355 : 1, 5, 71, 355
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,244,355,976, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
244:2x 2x 61
355:5x 71
976:2x 2x 2x 2x 61
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 61 = 488
Therefore, the value for common factors is 488.
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 = 35338188160/(1x488)
LCM = 35338188160/488
LCM = 72414320
Thus, we can understand that the LCM of 418,244,355,976 is 72414320.
