Given numbers are 437,921,817,478,215
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,921,817,478,215 is 41362561290.
Find LCM of 437,921,817,478,215 with Prime Factorization
| 19 | 437, 921, 817, 478, 215 |
| 43 | 23, 921, 43, 478, 215 |
| 23, 921, 1, 478, 5 |
Multiply the prime numbers at the bottom and the left side.
19 x 43 x 23 x 921 x 1 x 478 x 5 = 41362561290
Therefore, the lowest common multiple of 437,921,817,478,215 is 41362561290.
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.
437 x 921 x 817 x 478 x 215 = 33793212573930
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.
437 : 1, 19, 23, 437
921 : 1, 3, 307, 921
817 : 1, 19, 43, 817
478 : 1, 2, 239, 478
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,921,817,478,215, is 1.
Now, the common factors can be found like this.
437:19x 23
921:3x 307
817:19x 43
478:2x 239
215:5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 43 = 817
Therefore, the value for common factors is 817.
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 = 33793212573930/(1x817)
LCM = 33793212573930/817
LCM = 41362561290
Thus, we can understand that the LCM of 437,921,817,478,215 is 41362561290.
