Given numbers are 318,771,921,354
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 318,771,921,354 is 1480303038.
Find LCM of 318,771,921,354 with Prime Factorization
| 2 | 318, 771, 921, 354 |
| 3 | 159, 771, 921, 177 |
| 53, 257, 307, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 53 x 257 x 307 x 59 = 1480303038
Therefore, the lowest common multiple of 318,771,921,354 is 1480303038.
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.
318 x 771 x 921 x 354 = 79936364052
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.
318 : 1, 2, 3, 6, 53, 106, 159, 318
771 : 1, 3, 257, 771
921 : 1, 3, 307, 921
354 : 1, 2, 3, 6, 59, 118, 177, 354
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 318,771,921,354, is 3.
Now, the common factors can be found like this.
318:2x 3x 53
771:3x 257
921:3x 307
354:2x 3x 59
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 3 = 18
Therefore, the value for common factors is 18.
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 = 79936364052/(3x18)
LCM = 79936364052/54
LCM = 1480303038
Thus, we can understand that the LCM of 318,771,921,354 is 1480303038.
