Given numbers are 874,110,657,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,110,657,643 is 20307219570.
Find LCM of 874,110,657,643 with Prime Factorization
| 2 | 874, 110, 657, 643 |
| 437, 55, 657, 643 |
Multiply the prime numbers at the bottom and the left side.
2 x 437 x 55 x 657 x 643 = 20307219570
Therefore, the lowest common multiple of 874,110,657,643 is 20307219570.
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 110 x 657 x 643 = 40614439140
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
110 : 1, 2, 5, 10, 11, 22, 55, 110
657 : 1, 3, 9, 73, 219, 657
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,110,657,643, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
110:2x 5x 11
657:3x 3x 73
643:643
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 = 40614439140/(1x2)
LCM = 40614439140/2
LCM = 20307219570
Thus, we can understand that the LCM of 874,110,657,643 is 20307219570.
