Given numbers are 974,826,354,672
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 974,826,354,672 is 19308576.
Find LCM of 974,826,354,672 with Prime Factorization
| 2 | 974, 826, 354, 672 |
| 3 | 487, 413, 177, 336 |
| 7 | 487, 413, 59, 112 |
| 59 | 487, 59, 59, 16 |
| 487, 1, 1, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 59 x 487 x 1 x 1 x 16 = 19308576
Therefore, the lowest common multiple of 974,826,354,672 is 19308576.
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.
974 x 826 x 354 x 672 = 191386605312
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.
974 : 1, 2, 487, 974
826 : 1, 2, 7, 14, 59, 118, 413, 826
354 : 1, 2, 3, 6, 59, 118, 177, 354
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
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,826,354,672, is 2.
Now, the common factors can be found like this.
974:2x 487
826:2x 7x 59
354:2x 3x 59
672:2x 2x 2x 2x 2x 3x 7
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 7x 59 = 4956
Therefore, the value for common factors is 4956.
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 = 191386605312/(2x4956)
LCM = 191386605312/9912
LCM = 19308576
Thus, we can understand that the LCM of 974,826,354,672 is 19308576.
