Given numbers are 672,428,671,522
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 672,428,671,522 is 4197539808.
Find LCM of 672,428,671,522 with Prime Factorization
| 2 | 672, 428, 671, 522 |
| 2 | 336, 214, 671, 261 |
| 3 | 168, 107, 671, 261 |
| 56, 107, 671, 87 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 56 x 107 x 671 x 87 = 4197539808
Therefore, the lowest common multiple of 672,428,671,522 is 4197539808.
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.
672 x 428 x 671 x 522 = 100740955392
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.
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
428 : 1, 2, 4, 107, 214, 428
671 : 1, 11, 61, 671
522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,428,671,522, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
428:2x 2x 107
671:11x 61
522:2x 3x 3x 29
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 3 = 24
Therefore, the value for common factors is 24.
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 = 100740955392/(1x24)
LCM = 100740955392/24
LCM = 4197539808
Thus, we can understand that the LCM of 672,428,671,522 is 4197539808.
