Find LCM of 358,818,861,621,945 with Prime Factorization
2 | 358, 818, 861, 621, 945 |
3 | 179, 409, 861, 621, 945 |
3 | 179, 409, 287, 207, 315 |
3 | 179, 409, 287, 69, 105 |
7 | 179, 409, 287, 23, 35 |
179, 409, 41, 23, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 179 x 409 x 41 x 23 x 5 = 130481768970
Therefore, the lowest common multiple of 358,818,861,621,945 is 130481768970.
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.
358 x 818 x 861 x 621 x 945 = 147966326011980
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.
358 : 1, 2, 179, 358
818 : 1, 2, 409, 818
861 : 1, 3, 7, 21, 41, 123, 287, 861
621 : 1, 3, 9, 23, 27, 69, 207, 621
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 358,818,861,621,945, is 1.
Now, the common factors can be found like this.
358:2x 179
818:2x 409
861:3x 7x 41
621:3x 3x 3x 23
945:3x 3x 3x 5x 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 3x 3x 3x 3x 7 = 1134
Therefore, the value for common factors is 1134.
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 = 147966326011980/(1x1134)
LCM = 147966326011980/1134
LCM = 130481768970
Thus, we can understand that the LCM of 358,818,861,621,945 is 130481768970.
