Given numbers are 731,878,266,980,396
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,878,266,980,396 is 591557232420.
Find LCM of 731,878,266,980,396 with Prime Factorization
| 2 | 731, 878, 266, 980, 396 |
| 2 | 731, 439, 133, 490, 198 |
| 7 | 731, 439, 133, 245, 99 |
| 731, 439, 19, 35, 99 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 731 x 439 x 19 x 35 x 99 = 591557232420
Therefore, the lowest common multiple of 731,878,266,980,396 is 591557232420.
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.
731 x 878 x 266 x 980 x 396 = 66254410031040
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.
731 : 1, 17, 43, 731
878 : 1, 2, 439, 878
266 : 1, 2, 7, 14, 19, 38, 133, 266
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,878,266,980,396, is 1.
Now, the common factors can be found like this.
731:17x 43
878:2x 439
266:2x 7x 19
980:2x 2x 5x 7x 7
396:2x 2x 3x 3x 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 2x 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 66254410031040/(1x112)
LCM = 66254410031040/112
LCM = 591557232420
Thus, we can understand that the LCM of 731,878,266,980,396 is 591557232420.
