Given numbers are 707,309,204,686,974
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 707,309,204,686,974 is 354496414692.
Find LCM of 707,309,204,686,974 with Prime Factorization
| 2 | 707, 309, 204, 686, 974 |
| 3 | 707, 309, 102, 343, 487 |
| 7 | 707, 103, 34, 343, 487 |
| 101, 103, 34, 49, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 101 x 103 x 34 x 49 x 487 = 354496414692
Therefore, the lowest common multiple of 707,309,204,686,974 is 354496414692.
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.
707 x 309 x 204 x 686 x 974 = 29777698834128
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.
707 : 1, 7, 101, 707
309 : 1, 3, 103, 309
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
686 : 1, 2, 7, 14, 49, 98, 343, 686
974 : 1, 2, 487, 974
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 707,309,204,686,974, is 1.
Now, the common factors can be found like this.
707:7x 101
309:3x 103
204:2x 2x 3x 17
686:2x 7x 7x 7
974:2x 487
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 7 = 84
Therefore, the value for common factors is 84.
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 = 29777698834128/(1x84)
LCM = 29777698834128/84
LCM = 354496414692
Thus, we can understand that the LCM of 707,309,204,686,974 is 354496414692.
