Given numbers are 402,678,123,353
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 402,678,123,353 is 657450498.
Find LCM of 402,678,123,353 with Prime Factorization
2 | 402, 678, 123, 353 |
3 | 201, 339, 123, 353 |
67, 113, 41, 353 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 67 x 113 x 41 x 353 = 657450498
Therefore, the lowest common multiple of 402,678,123,353 is 657450498.
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.
402 x 678 x 123 x 353 = 11834108964
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.
402 : 1, 2, 3, 6, 67, 134, 201, 402
678 : 1, 2, 3, 6, 113, 226, 339, 678
123 : 1, 3, 41, 123
353 : 1, 353
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,678,123,353, is 1.
Now, the common factors can be found like this.
402:2x 3x 67
678:2x 3x 113
123:3x 41
353:353
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 3 = 18
Therefore, the value for common factors is 18.
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 = 11834108964/(1x18)
LCM = 11834108964/18
LCM = 657450498
Thus, we can understand that the LCM of 402,678,123,353 is 657450498.
