Given numbers are 277,465,784,258,445
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 277,465,784,258,445 is 386462400240.
Find LCM of 277,465,784,258,445 with Prime Factorization
| 2 | 277, 465, 784, 258, 445 |
| 3 | 277, 465, 392, 129, 445 |
| 5 | 277, 155, 392, 43, 445 |
| 277, 31, 392, 43, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 277 x 31 x 392 x 43 x 89 = 386462400240
Therefore, the lowest common multiple of 277,465,784,258,445 is 386462400240.
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.
277 x 465 x 784 x 258 x 445 = 11593872007200
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.
277 : 1, 277
465 : 1, 3, 5, 15, 31, 93, 155, 465
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
258 : 1, 2, 3, 6, 43, 86, 129, 258
445 : 1, 5, 89, 445
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 277,465,784,258,445, is 1.
Now, the common factors can be found like this.
277:277
465:3x 5x 31
784:2x 2x 2x 2x 7x 7
258:2x 3x 43
445:5x 89
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 5 = 30
Therefore, the value for common factors is 30.
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 = 11593872007200/(1x30)
LCM = 11593872007200/30
LCM = 386462400240
Thus, we can understand that the LCM of 277,465,784,258,445 is 386462400240.
