| 23 | 23, 32, 821, 69, 1 |
| 1, 32, 821, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 17 x 23 x 1 x 32 x 821 x 3 x 1 = 1479218688
Therefore, the lowest common multiple of 782,512,821,207,816 is 1479218688.
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.
782 x 512 x 821 x 207 x 816 = 55523952672768
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
821 : 1, 821
207 : 1, 3, 9, 23, 69, 207
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,512,821,207,816, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
512:2x 2x 2x 2x 2x 2x 2x 2x 2
821:821
207:3x 3x 23
816:2x 2x 2x 2x 3x 17
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 2x 3x 17x 23 = 37536
Therefore, the value for common factors is 37536.
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 = 55523952672768/(1x37536)
LCM = 55523952672768/37536
LCM = 1479218688
Thus, we can understand that the LCM of 782,512,821,207,816 is 1479218688.
