Given numbers are 294,510,445,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 294,510,445,645 is 95636730.
Find LCM of 294,510,445,645 with Prime Factorization
| 2 | 294, 510, 445, 645 |
| 3 | 147, 255, 445, 645 |
| 5 | 49, 85, 445, 215 |
| 49, 17, 89, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 49 x 17 x 89 x 43 = 95636730
Therefore, the lowest common multiple of 294,510,445,645 is 95636730.
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.
294 x 510 x 445 x 645 = 43036528500
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.
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
445 : 1, 5, 89, 445
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 294,510,445,645, is 1.
Now, the common factors can be found like this.
294:2x 3x 7x 7
510:2x 3x 5x 17
445:5x 89
645:3x 5x 43
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 3x 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 43036528500/(1x450)
LCM = 43036528500/450
LCM = 95636730
Thus, we can understand that the LCM of 294,510,445,645 is 95636730.
