Given numbers are 874,803,642,692,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,803,642,692,242 is 857434184772.
Find LCM of 874,803,642,692,242 with Prime Factorization
| 2 | 874, 803, 642, 692, 242 |
| 11 | 437, 803, 321, 346, 121 |
| 437, 73, 321, 346, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 437 x 73 x 321 x 346 x 11 = 857434184772
Therefore, the lowest common multiple of 874,803,642,692,242 is 857434184772.
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.
874 x 803 x 642 x 692 x 242 = 75454208259936
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
803 : 1, 11, 73, 803
642 : 1, 2, 3, 6, 107, 214, 321, 642
692 : 1, 2, 4, 173, 346, 692
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,803,642,692,242, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
803:11x 73
642:2x 3x 107
692:2x 2x 173
242:2x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 11 = 88
Therefore, the value for common factors is 88.
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 = 75454208259936/(1x88)
LCM = 75454208259936/88
LCM = 857434184772
Thus, we can understand that the LCM of 874,803,642,692,242 is 857434184772.
