Given numbers are 210,693,671,213
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 210,693,671,213 is 30013830.
Find LCM of 210,693,671,213 with Prime Factorization
| 3 | 210, 693, 671, 213 |
| 7 | 70, 231, 671, 71 |
| 11 | 10, 33, 671, 71 |
| 10, 3, 61, 71 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 10 x 3 x 61 x 71 = 30013830
Therefore, the lowest common multiple of 210,693,671,213 is 30013830.
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.
210 x 693 x 671 x 213 = 20799584190
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.
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
671 : 1, 11, 61, 671
213 : 1, 3, 71, 213
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,693,671,213, is 1.
Now, the common factors can be found like this.
210:2x 3x 5x 7
693:3x 3x 7x 11
671:11x 61
213:3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7x 11 = 693
Therefore, the value for common factors is 693.
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 = 20799584190/(1x693)
LCM = 20799584190/693
LCM = 30013830
Thus, we can understand that the LCM of 210,693,671,213 is 30013830.
