Given numbers are 407,402,308,458
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 407,402,308,458 is 524546484.
Find LCM of 407,402,308,458 with Prime Factorization
| 2 | 407, 402, 308, 458 |
| 11 | 407, 201, 154, 229 |
| 37, 201, 14, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 37 x 201 x 14 x 229 = 524546484
Therefore, the lowest common multiple of 407,402,308,458 is 524546484.
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.
407 x 402 x 308 x 458 = 23080045296
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.
407 : 1, 11, 37, 407
402 : 1, 2, 3, 6, 67, 134, 201, 402
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
458 : 1, 2, 229, 458
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,402,308,458, is 1.
Now, the common factors can be found like this.
407:11x 37
402:2x 3x 67
308:2x 2x 7x 11
458:2x 229
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 11 = 44
Therefore, the value for common factors is 44.
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 = 23080045296/(1x44)
LCM = 23080045296/44
LCM = 524546484
Thus, we can understand that the LCM of 407,402,308,458 is 524546484.
