Given numbers are 1470,6891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 1470,6891 is 3376590.
Find LCM of 1470,6891 with Prime Factorization
| 3 | 1470, 6891 |
| 490, 2297 |
Multiply the prime numbers at the bottom and the left side.
3 x 490 x 2297 = 3376590
Therefore, the lowest common multiple of 1470,6891 is 3376590.
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.
1470 x 6891 = 10129770
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.
1470 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 49, 70, 98, 105, 147, 210, 245, 294, 490, 735, 1470
6891 : 1, 3, 2297, 6891
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1470,6891, is 3.
Now, the common factors can be found like this.
1470:2x 3x 5x 7x 7
6891:3x 2297
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
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 = 10129770/(3x1)
LCM = 10129770/3
LCM = 3376590
Thus, we can understand that the LCM of 1470,6891 is 3376590.
