Given numbers are 643,803,654,212
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,803,654,212 is 35793991596.
Find LCM of 643,803,654,212 with Prime Factorization
2 | 643, 803, 654, 212 |
643, 803, 327, 106 |
Multiply the prime numbers at the bottom and the left side.
2 x 643 x 803 x 327 x 106 = 35793991596
Therefore, the lowest common multiple of 643,803,654,212 is 35793991596.
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.
643 x 803 x 654 x 212 = 71587983192
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.
643 : 1, 643
803 : 1, 11, 73, 803
654 : 1, 2, 3, 6, 109, 218, 327, 654
212 : 1, 2, 4, 53, 106, 212
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,803,654,212, is 1.
Now, the common factors can be found like this.
643:643
803:11x 73
654:2x 3x 109
212:2x 2x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 71587983192/(1x2)
LCM = 71587983192/2
LCM = 35793991596
Thus, we can understand that the LCM of 643,803,654,212 is 35793991596.
