Find LCM of 280,782,854,506,215 with Prime Factorization
2 | 280, 782, 854, 506, 215 |
5 | 140, 391, 427, 253, 215 |
7 | 28, 391, 427, 253, 43 |
23 | 4, 391, 61, 253, 43 |
4, 17, 61, 11, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 23 x 4 x 17 x 61 x 11 x 43 = 3158826440
Therefore, the lowest common multiple of 280,782,854,506,215 is 3158826440.
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.
280 x 782 x 854 x 506 x 215 = 20342842273600
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
782 : 1, 2, 17, 23, 34, 46, 391, 782
854 : 1, 2, 7, 14, 61, 122, 427, 854
506 : 1, 2, 11, 22, 23, 46, 253, 506
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,782,854,506,215, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
782:2x 17x 23
854:2x 7x 61
506:2x 11x 23
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.
2x 2x 2x 5x 7x 23 = 6440
Therefore, the value for common factors is 6440.
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 = 20342842273600/(1x6440)
LCM = 20342842273600/6440
LCM = 3158826440
Thus, we can understand that the LCM of 280,782,854,506,215 is 3158826440.
