Given numbers are 647,754,986,612
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,754,986,612 is 149278428.
Find LCM of 647,754,986,612 with Prime Factorization
| 2 | 647, 754, 986, 612 |
| 17 | 647, 377, 493, 306 |
| 29 | 647, 377, 29, 18 |
| 647, 13, 1, 18 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 29 x 647 x 13 x 1 x 18 = 149278428
Therefore, the lowest common multiple of 647,754,986,612 is 149278428.
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.
647 x 754 x 986 x 612 = 294377060016
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.
647 : 1, 647
754 : 1, 2, 13, 26, 29, 58, 377, 754
986 : 1, 2, 17, 29, 34, 58, 493, 986
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,754,986,612, is 1.
Now, the common factors can be found like this.
647:647
754:2x 13x 29
986:2x 17x 29
612:2x 2x 3x 3x 17
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 17x 29 = 1972
Therefore, the value for common factors is 1972.
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 = 294377060016/(1x1972)
LCM = 294377060016/1972
LCM = 149278428
Thus, we can understand that the LCM of 647,754,986,612 is 149278428.
