Given numbers are 645,953,323,306,336
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 645,953,323,306,336 is 66710533680.
Find LCM of 645,953,323,306,336 with Prime Factorization
| 2 | 645, 953, 323, 306, 336 |
| 3 | 645, 953, 323, 153, 168 |
| 17 | 215, 953, 323, 51, 56 |
| 215, 953, 19, 3, 56 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 215 x 953 x 19 x 3 x 56 = 66710533680
Therefore, the lowest common multiple of 645,953,323,306,336 is 66710533680.
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.
645 x 953 x 323 x 306 x 336 = 20413423306080
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.
645 : 1, 3, 5, 15, 43, 129, 215, 645
953 : 1, 953
323 : 1, 17, 19, 323
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,953,323,306,336, is 1.
Now, the common factors can be found like this.
645:3x 5x 43
953:953
323:17x 19
306:2x 3x 3x 17
336:2x 2x 2x 2x 3x 7
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 17 = 306
Therefore, the value for common factors is 306.
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 = 20413423306080/(1x306)
LCM = 20413423306080/306
LCM = 66710533680
Thus, we can understand that the LCM of 645,953,323,306,336 is 66710533680.
