Given numbers are 655,294,623,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,294,623,987 is 805520310.
Find LCM of 655,294,623,987 with Prime Factorization
| 3 | 655, 294, 623, 987 |
| 7 | 655, 98, 623, 329 |
| 655, 14, 89, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 655 x 14 x 89 x 47 = 805520310
Therefore, the lowest common multiple of 655,294,623,987 is 805520310.
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.
655 x 294 x 623 x 987 = 118411485570
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.
655 : 1, 5, 131, 655
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
623 : 1, 7, 89, 623
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,294,623,987, is 1.
Now, the common factors can be found like this.
655:5x 131
294:2x 3x 7x 7
623:7x 89
987:3x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 118411485570/(1x147)
LCM = 118411485570/147
LCM = 805520310
Thus, we can understand that the LCM of 655,294,623,987 is 805520310.
