Given numbers are 665,285,376,209,949
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,285,376,209,949 is 7830502680.
Find LCM of 665,285,376,209,949 with Prime Factorization
5 | 665, 285, 376, 209, 949 |
19 | 133, 57, 376, 209, 949 |
7, 3, 376, 11, 949 |
Multiply the prime numbers at the bottom and the left side.
5 x 19 x 7 x 3 x 376 x 11 x 949 = 7830502680
Therefore, the lowest common multiple of 665,285,376,209,949 is 7830502680.
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.
665 x 285 x 376 x 209 x 949 = 14134057337400
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
285 : 1, 3, 5, 15, 19, 57, 95, 285
376 : 1, 2, 4, 8, 47, 94, 188, 376
209 : 1, 11, 19, 209
949 : 1, 13, 73, 949
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,285,376,209,949, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
285:3x 5x 19
376:2x 2x 2x 47
209:11x 19
949:13x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 19x 19 = 1805
Therefore, the value for common factors is 1805.
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 = 14134057337400/(1x1805)
LCM = 14134057337400/1805
LCM = 7830502680
Thus, we can understand that the LCM of 665,285,376,209,949 is 7830502680.
