Given numbers are 427,638,309,343,336
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 427,638,309,343,336 is 32998416528.
Find LCM of 427,638,309,343,336 with Prime Factorization
| 2 | 427, 638, 309, 343, 336 |
| 3 | 427, 319, 309, 343, 168 |
| 7 | 427, 319, 103, 343, 56 |
| 61, 319, 103, 49, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 61 x 319 x 103 x 49 x 8 = 32998416528
Therefore, the lowest common multiple of 427,638,309,343,336 is 32998416528.
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.
427 x 638 x 309 x 343 x 336 = 9701534459232
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.
427 : 1, 7, 61, 427
638 : 1, 2, 11, 22, 29, 58, 319, 638
309 : 1, 3, 103, 309
343 : 1, 7, 49, 343
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,638,309,343,336, is 1.
Now, the common factors can be found like this.
427:7x 61
638:2x 11x 29
309:3x 103
343:7x 7x 7
336:2x 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 3x 7x 7 = 294
Therefore, the value for common factors is 294.
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 = 9701534459232/(1x294)
LCM = 9701534459232/294
LCM = 32998416528
Thus, we can understand that the LCM of 427,638,309,343,336 is 32998416528.
