Given numbers are 821,354,510,908,948
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,354,510,908,948 is 886029718740.
Find LCM of 821,354,510,908,948 with Prime Factorization
| 2 | 821, 354, 510, 908, 948 |
| 2 | 821, 177, 255, 454, 474 |
| 3 | 821, 177, 255, 227, 237 |
| 821, 59, 85, 227, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 821 x 59 x 85 x 227 x 79 = 886029718740
Therefore, the lowest common multiple of 821,354,510,908,948 is 886029718740.
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.
821 x 354 x 510 x 908 x 948 = 127588279498560
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.
821 : 1, 821
354 : 1, 2, 3, 6, 59, 118, 177, 354
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
908 : 1, 2, 4, 227, 454, 908
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,354,510,908,948, is 1.
Now, the common factors can be found like this.
821:821
354:2x 3x 59
510:2x 3x 5x 17
908:2x 2x 227
948:2x 2x 3x 79
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 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 127588279498560/(1x144)
LCM = 127588279498560/144
LCM = 886029718740
Thus, we can understand that the LCM of 821,354,510,908,948 is 886029718740.
