Given numbers are 469,100,670,785,942
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 469,100,670,785,942 is 22089900.
Find LCM of 469,100,670,785,942 with Prime Factorization
| 2 | 469, 100, 670, 785, 942 |
| 5 | 469, 50, 335, 785, 471 |
| 67 | 469, 10, 67, 157, 471 |
| 157 | 7, 10, 1, 157, 471 |
| 7, 10, 1, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 67 x 157 x 7 x 10 x 1 x 1 x 3 = 22089900
Therefore, the lowest common multiple of 469,100,670,785,942 is 22089900.
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.
469 x 100 x 670 x 785 x 942 = 23236365810000
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.
469 : 1, 7, 67, 469
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
670 : 1, 2, 5, 10, 67, 134, 335, 670
785 : 1, 5, 157, 785
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 469,100,670,785,942, is 1.
Now, the common factors can be found like this.
469:7x 67
100:2x 2x 5x 5
670:2x 5x 67
785:5x 157
942:2x 3x 157
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 5x 5x 67x 157 = 1051900
Therefore, the value for common factors is 1051900.
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 = 23236365810000/(1x1051900)
LCM = 23236365810000/1051900
LCM = 22089900
Thus, we can understand that the LCM of 469,100,670,785,942 is 22089900.
