Given numbers are 471,428,802,764
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 471,428,802,764 is 15439826508.
Find LCM of 471,428,802,764 with Prime Factorization
| 2 | 471, 428, 802, 764 |
| 2 | 471, 214, 401, 382 |
| 471, 107, 401, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 471 x 107 x 401 x 191 = 15439826508
Therefore, the lowest common multiple of 471,428,802,764 is 15439826508.
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.
471 x 428 x 802 x 764 = 123518612064
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.
471 : 1, 3, 157, 471
428 : 1, 2, 4, 107, 214, 428
802 : 1, 2, 401, 802
764 : 1, 2, 4, 191, 382, 764
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 471,428,802,764, is 1.
Now, the common factors can be found like this.
471:3x 157
428:2x 2x 107
802:2x 401
764:2x 2x 191
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 2 = 8
Therefore, the value for common factors is 8.
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 = 123518612064/(1x8)
LCM = 123518612064/8
LCM = 15439826508
Thus, we can understand that the LCM of 471,428,802,764 is 15439826508.
