Given numbers are 474,614,974,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 474,614,974,690 is 8149735590.
Find LCM of 474,614,974,690 with Prime Factorization
| 2 | 474, 614, 974, 690 |
| 3 | 237, 307, 487, 345 |
| 79, 307, 487, 115 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 79 x 307 x 487 x 115 = 8149735590
Therefore, the lowest common multiple of 474,614,974,690 is 8149735590.
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.
474 x 614 x 974 x 690 = 195593654160
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.
474 : 1, 2, 3, 6, 79, 158, 237, 474
614 : 1, 2, 307, 614
974 : 1, 2, 487, 974
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 474,614,974,690, is 2.
Now, the common factors can be found like this.
474:2x 3x 79
614:2x 307
974:2x 487
690:2x 3x 5x 23
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 3 = 12
Therefore, the value for common factors is 12.
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 = 195593654160/(2x12)
LCM = 195593654160/24
LCM = 8149735590
Thus, we can understand that the LCM of 474,614,974,690 is 8149735590.
