Given numbers are 906,645,818,361,672
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 906,645,818,361,672 is 3221181455520.
Find LCM of 906,645,818,361,672 with Prime Factorization
| 2 | 906, 645, 818, 361, 672 |
| 3 | 453, 645, 409, 361, 336 |
| 151, 215, 409, 361, 112 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 151 x 215 x 409 x 361 x 112 = 3221181455520
Therefore, the lowest common multiple of 906,645,818,361,672 is 3221181455520.
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.
906 x 645 x 818 x 361 x 672 = 115962532398720
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.
906 : 1, 2, 3, 6, 151, 302, 453, 906
645 : 1, 3, 5, 15, 43, 129, 215, 645
818 : 1, 2, 409, 818
361 : 1, 19, 361
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,645,818,361,672, is 1.
Now, the common factors can be found like this.
906:2x 3x 151
645:3x 5x 43
818:2x 409
361:19x 19
672:2x 2x 2x 2x 2x 3x 7
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 115962532398720/(1x36)
LCM = 115962532398720/36
LCM = 3221181455520
Thus, we can understand that the LCM of 906,645,818,361,672 is 3221181455520.
