Given numbers are 893,431,862,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 893,431,862,648 is 249404184.
Find LCM of 893,431,862,648 with Prime Factorization
| 2 | 893, 431, 862, 648 |
| 431 | 893, 431, 431, 324 |
| 893, 1, 1, 324 |
Multiply the prime numbers at the bottom and the left side.
2 x 431 x 893 x 1 x 1 x 324 = 249404184
Therefore, the lowest common multiple of 893,431,862,648 is 249404184.
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.
893 x 431 x 862 x 648 = 214986406608
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.
893 : 1, 19, 47, 893
431 : 1, 431
862 : 1, 2, 431, 862
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 893,431,862,648, is 1.
Now, the common factors can be found like this.
893:19x 47
431:431
862:2x 431
648:2x 2x 2x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 431 = 862
Therefore, the value for common factors is 862.
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 = 214986406608/(1x862)
LCM = 214986406608/862
LCM = 249404184
Thus, we can understand that the LCM of 893,431,862,648 is 249404184.
