Given numbers are 766,396,286,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 766,396,286,770 is 69008940.
Find LCM of 766,396,286,770 with Prime Factorization
| 2 | 766, 396, 286, 770 |
| 11 | 383, 198, 143, 385 |
| 383, 18, 13, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 383 x 18 x 13 x 35 = 69008940
Therefore, the lowest common multiple of 766,396,286,770 is 69008940.
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.
766 x 396 x 286 x 770 = 66800653920
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.
766 : 1, 2, 383, 766
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
286 : 1, 2, 11, 13, 22, 26, 143, 286
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 766,396,286,770, is 2.
Now, the common factors can be found like this.
766:2x 383
396:2x 2x 3x 3x 11
286:2x 11x 13
770:2x 5x 7x 11
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 11 = 484
Therefore, the value for common factors is 484.
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 = 66800653920/(2x484)
LCM = 66800653920/968
LCM = 69008940
Thus, we can understand that the LCM of 766,396,286,770 is 69008940.
