Given numbers are 212,690,943,138,531
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 212,690,943,138,531 is 530776980.
Find LCM of 212,690,943,138,531 with Prime Factorization
| 2 | 212, 690, 943, 138, 531 |
| 3 | 106, 345, 943, 69, 531 |
| 23 | 106, 115, 943, 23, 177 |
| 106, 5, 41, 1, 177 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 106 x 5 x 41 x 1 x 177 = 530776980
Therefore, the lowest common multiple of 212,690,943,138,531 is 530776980.
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 690 x 943 x 138 x 531 = 10108116807120
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
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
943 : 1, 23, 41, 943
138 : 1, 2, 3, 6, 23, 46, 69, 138
531 : 1, 3, 9, 59, 177, 531
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,690,943,138,531, is 1.
Now, the common factors can be found like this.
212:2x 2x 53
690:2x 3x 5x 23
943:23x 41
138:2x 3x 23
531:3x 3x 59
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 3x 23x 23 = 19044
Therefore, the value for common factors is 19044.
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 = 10108116807120/(1x19044)
LCM = 10108116807120/19044
LCM = 530776980
Thus, we can understand that the LCM of 212,690,943,138,531 is 530776980.
