Given numbers are 434,506,682,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 434,506,682,748 is 3733268.
Find LCM of 434,506,682,748 with Prime Factorization
| 2 | 434, 506, 682, 748 |
| 11 | 217, 253, 341, 374 |
| 31 | 217, 23, 31, 34 |
| 7, 23, 1, 34 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 31 x 7 x 23 x 1 x 34 = 3733268
Therefore, the lowest common multiple of 434,506,682,748 is 3733268.
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.
434 x 506 x 682 x 748 = 112027906144
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.
434 : 1, 2, 7, 14, 31, 62, 217, 434
506 : 1, 2, 11, 22, 23, 46, 253, 506
682 : 1, 2, 11, 22, 31, 62, 341, 682
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 434,506,682,748, is 2.
Now, the common factors can be found like this.
434:2x 7x 31
506:2x 11x 23
682:2x 11x 31
748:2x 2x 11x 17
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 11x 11x 31 = 15004
Therefore, the value for common factors is 15004.
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 = 112027906144/(2x15004)
LCM = 112027906144/30008
LCM = 3733268
Thus, we can understand that the LCM of 434,506,682,748 is 3733268.
