Given numbers are 921,308,731,754
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,308,731,754 is 78175213116.
Find LCM of 921,308,731,754 with Prime Factorization
| 2 | 921, 308, 731, 754 |
| 921, 154, 731, 377 |
Multiply the prime numbers at the bottom and the left side.
2 x 921 x 154 x 731 x 377 = 78175213116
Therefore, the lowest common multiple of 921,308,731,754 is 78175213116.
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.
921 x 308 x 731 x 754 = 156350426232
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.
921 : 1, 3, 307, 921
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
731 : 1, 17, 43, 731
754 : 1, 2, 13, 26, 29, 58, 377, 754
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,308,731,754, is 1.
Now, the common factors can be found like this.
921:3x 307
308:2x 2x 7x 11
731:17x 43
754:2x 13x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 156350426232/(1x2)
LCM = 156350426232/2
LCM = 78175213116
Thus, we can understand that the LCM of 921,308,731,754 is 78175213116.
