Given numbers are 212,689,842
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 212,689,842 is 1160276.
Find LCM of 212,689,842 with Prime Factorization
| 2 | 212, 689, 842 |
| 53 | 106, 689, 421 |
| 2, 13, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 53 x 2 x 13 x 421 = 1160276
Therefore, the lowest common multiple of 212,689,842 is 1160276.
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.
212 x 689 x 842 = 122989256
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.
212 : 1, 2, 4, 53, 106, 212
689 : 1, 13, 53, 689
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,689,842, is 1.
Now, the common factors can be found like this.
212:2x 2x 53
689:13x 53
842:2x 421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 53 = 106
Therefore, the value for common factors is 106.
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 = 122989256/(1x106)
LCM = 122989256/106
LCM = 1160276
Thus, we can understand that the LCM of 212,689,842 is 1160276.
