Given numbers are 426,316,678,249
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 426,316,678,249 is 631281732.
Find LCM of 426,316,678,249 with Prime Factorization
| 2 | 426, 316, 678, 249 |
| 3 | 213, 158, 339, 249 |
| 71, 158, 113, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 71 x 158 x 113 x 83 = 631281732
Therefore, the lowest common multiple of 426,316,678,249 is 631281732.
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.
426 x 316 x 678 x 249 = 22726142352
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.
426 : 1, 2, 3, 6, 71, 142, 213, 426
316 : 1, 2, 4, 79, 158, 316
678 : 1, 2, 3, 6, 113, 226, 339, 678
249 : 1, 3, 83, 249
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,316,678,249, is 1.
Now, the common factors can be found like this.
426:2x 3x 71
316:2x 2x 79
678:2x 3x 113
249:3x 83
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 22726142352/(1x36)
LCM = 22726142352/36
LCM = 631281732
Thus, we can understand that the LCM of 426,316,678,249 is 631281732.
