Given numbers are 694,154,561,312
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 694,154,561,312 is 141717576.
Find LCM of 694,154,561,312 with Prime Factorization
| 2 | 694, 154, 561, 312 |
| 3 | 347, 77, 561, 156 |
| 11 | 347, 77, 187, 52 |
| 347, 7, 17, 52 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 347 x 7 x 17 x 52 = 141717576
Therefore, the lowest common multiple of 694,154,561,312 is 141717576.
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.
694 x 154 x 561 x 312 = 18706720032
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.
694 : 1, 2, 347, 694
154 : 1, 2, 7, 11, 14, 22, 77, 154
561 : 1, 3, 11, 17, 33, 51, 187, 561
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 694,154,561,312, is 1.
Now, the common factors can be found like this.
694:2x 347
154:2x 7x 11
561:3x 11x 17
312:2x 2x 2x 3x 13
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 11 = 132
Therefore, the value for common factors is 132.
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 = 18706720032/(1x132)
LCM = 18706720032/132
LCM = 141717576
Thus, we can understand that the LCM of 694,154,561,312 is 141717576.
