Given numbers are 801,217,770,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 801,217,770,946 is 822154410.
Find LCM of 801,217,770,946 with Prime Factorization
| 2 | 801, 217, 770, 946 |
| 7 | 801, 217, 385, 473 |
| 11 | 801, 31, 55, 473 |
| 801, 31, 5, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 801 x 31 x 5 x 43 = 822154410
Therefore, the lowest common multiple of 801,217,770,946 is 822154410.
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.
801 x 217 x 770 x 946 = 126611779140
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.
801 : 1, 3, 9, 89, 267, 801
217 : 1, 7, 31, 217
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 801,217,770,946, is 1.
Now, the common factors can be found like this.
801:3x 3x 89
217:7x 31
770:2x 5x 7x 11
946:2x 11x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11 = 154
Therefore, the value for common factors is 154.
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 = 126611779140/(1x154)
LCM = 126611779140/154
LCM = 822154410
Thus, we can understand that the LCM of 801,217,770,946 is 822154410.
