Given numbers are 641,471,817,774
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 641,471,817,774 is 1479967722.
Find LCM of 641,471,817,774 with Prime Factorization
| 3 | 641, 471, 817, 774 |
| 43 | 641, 157, 817, 258 |
| 641, 157, 19, 6 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 641 x 157 x 19 x 6 = 1479967722
Therefore, the lowest common multiple of 641,471,817,774 is 1479967722.
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.
641 x 471 x 817 x 774 = 190915836138
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.
641 : 1, 641
471 : 1, 3, 157, 471
817 : 1, 19, 43, 817
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,471,817,774, is 1.
Now, the common factors can be found like this.
641:641
471:3x 157
817:19x 43
774:2x 3x 3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 43 = 129
Therefore, the value for common factors is 129.
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 = 190915836138/(1x129)
LCM = 190915836138/129
LCM = 1479967722
Thus, we can understand that the LCM of 641,471,817,774 is 1479967722.
