Given numbers are 428,356,376,142,284
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,356,376,142,284 is 254226008.
Find LCM of 428,356,376,142,284 with Prime Factorization
| 2 | 428, 356, 376, 142, 284 |
| 2 | 214, 178, 188, 71, 142 |
| 71 | 107, 89, 94, 71, 71 |
| 107, 89, 94, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 71 x 107 x 89 x 94 x 1 x 1 = 254226008
Therefore, the lowest common multiple of 428,356,376,142,284 is 254226008.
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.
428 x 356 x 376 x 142 x 284 = 2310405960704
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.
428 : 1, 2, 4, 107, 214, 428
356 : 1, 2, 4, 89, 178, 356
376 : 1, 2, 4, 8, 47, 94, 188, 376
142 : 1, 2, 71, 142
284 : 1, 2, 4, 71, 142, 284
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,356,376,142,284, is 2.
Now, the common factors can be found like this.
428:2x 2x 107
356:2x 2x 89
376:2x 2x 2x 47
142:2x 71
284:2x 2x 71
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 2x 2x 2x 71 = 4544
Therefore, the value for common factors is 4544.
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 = 2310405960704/(2x4544)
LCM = 2310405960704/9088
LCM = 254226008
Thus, we can understand that the LCM of 428,356,376,142,284 is 254226008.
