Given numbers are 969,689,427,506,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,689,427,506,442 is 144251849742.
Find LCM of 969,689,427,506,442 with Prime Factorization
| 2 | 969, 689, 427, 506, 442 |
| 13 | 969, 689, 427, 253, 221 |
| 17 | 969, 53, 427, 253, 17 |
| 57, 53, 427, 253, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 57 x 53 x 427 x 253 x 1 = 144251849742
Therefore, the lowest common multiple of 969,689,427,506,442 is 144251849742.
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.
969 x 689 x 427 x 506 x 442 = 63759317585964
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
689 : 1, 13, 53, 689
427 : 1, 7, 61, 427
506 : 1, 2, 11, 22, 23, 46, 253, 506
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,689,427,506,442, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
689:13x 53
427:7x 61
506:2x 11x 23
442:2x 13x 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 13x 17 = 442
Therefore, the value for common factors is 442.
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 = 63759317585964/(1x442)
LCM = 63759317585964/442
LCM = 144251849742
Thus, we can understand that the LCM of 969,689,427,506,442 is 144251849742.
