Given numbers are 905,969,817,306,694
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 905,969,817,306,694 is 78509378070.
Find LCM of 905,969,817,306,694 with Prime Factorization
| 2 | 905, 969, 817, 306, 694 |
| 3 | 905, 969, 817, 153, 347 |
| 17 | 905, 323, 817, 51, 347 |
| 19 | 905, 19, 817, 3, 347 |
| 905, 1, 43, 3, 347 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 19 x 905 x 1 x 43 x 3 x 347 = 78509378070
Therefore, the lowest common multiple of 905,969,817,306,694 is 78509378070.
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.
905 x 969 x 817 x 306 x 694 = 152151174699660
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.
905 : 1, 5, 181, 905
969 : 1, 3, 17, 19, 51, 57, 323, 969
817 : 1, 19, 43, 817
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
694 : 1, 2, 347, 694
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,969,817,306,694, is 1.
Now, the common factors can be found like this.
905:5x 181
969:3x 17x 19
817:19x 43
306:2x 3x 3x 17
694:2x 347
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17x 19 = 1938
Therefore, the value for common factors is 1938.
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 = 152151174699660/(1x1938)
LCM = 152151174699660/1938
LCM = 78509378070
Thus, we can understand that the LCM of 905,969,817,306,694 is 78509378070.
