| 13 | 13, 13, 33, 46, 421 |
| 1, 1, 33, 46, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 13 x 1 x 1 x 33 x 46 x 421 = 1794531024
Therefore, the lowest common multiple of 351,312,891,368,421 is 1794531024.
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.
351 x 312 x 891 x 368 x 421 = 15117129346176
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.
351 : 1, 3, 9, 13, 27, 39, 117, 351
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 351,312,891,368,421, is 1.
Now, the common factors can be found like this.
351:3x 3x 3x 13
312:2x 2x 2x 3x 13
891:3x 3x 3x 3x 11
368:2x 2x 2x 2x 23
421:421
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 3x 3x 3x 3x 13 = 8424
Therefore, the value for common factors is 8424.
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 = 15117129346176/(1x8424)
LCM = 15117129346176/8424
LCM = 1794531024
Thus, we can understand that the LCM of 351,312,891,368,421 is 1794531024.
