Given numbers are 428,536,404,707
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,536,404,707 is 40547864.
Find LCM of 428,536,404,707 with Prime Factorization
| 2 | 428, 536, 404, 707 |
| 2 | 214, 268, 202, 707 |
| 101 | 107, 134, 101, 707 |
| 107, 134, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 101 x 107 x 134 x 1 x 7 = 40547864
Therefore, the lowest common multiple of 428,536,404,707 is 40547864.
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.
428 x 536 x 404 x 707 = 65525348224
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.
428 : 1, 2, 4, 107, 214, 428
536 : 1, 2, 4, 8, 67, 134, 268, 536
404 : 1, 2, 4, 101, 202, 404
707 : 1, 7, 101, 707
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,536,404,707, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
536:2x 2x 2x 67
404:2x 2x 101
707:7x 101
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 2x 2x 101 = 1616
Therefore, the value for common factors is 1616.
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 = 65525348224/(1x1616)
LCM = 65525348224/1616
LCM = 40547864
Thus, we can understand that the LCM of 428,536,404,707 is 40547864.
