Given numbers are 874,780,258,703
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,780,258,703 is 542308260.
Find LCM of 874,780,258,703 with Prime Factorization
| 2 | 874, 780, 258, 703 |
| 3 | 437, 390, 129, 703 |
| 19 | 437, 130, 43, 703 |
| 23, 130, 43, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 23 x 130 x 43 x 37 = 542308260
Therefore, the lowest common multiple of 874,780,258,703 is 542308260.
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 780 x 258 x 703 = 123646283280
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
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
258 : 1, 2, 3, 6, 43, 86, 129, 258
703 : 1, 19, 37, 703
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,780,258,703, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
780:2x 2x 3x 5x 13
258:2x 3x 43
703:19x 37
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 3x 19 = 228
Therefore, the value for common factors is 228.
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 = 123646283280/(1x228)
LCM = 123646283280/228
LCM = 542308260
Thus, we can understand that the LCM of 874,780,258,703 is 542308260.
