Given numbers are 661,938,952,686,682
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,938,952,686,682 is 704471891816.
Find LCM of 661,938,952,686,682 with Prime Factorization
| 2 | 661, 938, 952, 686, 682 |
| 7 | 661, 469, 476, 343, 341 |
| 661, 67, 68, 49, 341 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 661 x 67 x 68 x 49 x 341 = 704471891816
Therefore, the lowest common multiple of 661,938,952,686,682 is 704471891816.
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.
661 x 938 x 952 x 686 x 682 = 276152981591872
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.
661 : 1, 661
938 : 1, 2, 7, 14, 67, 134, 469, 938
952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952
686 : 1, 2, 7, 14, 49, 98, 343, 686
682 : 1, 2, 11, 22, 31, 62, 341, 682
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,938,952,686,682, is 1.
Now, the common factors can be found like this.
661:661
938:2x 7x 67
952:2x 2x 2x 7x 17
686:2x 7x 7x 7
682:2x 11x 31
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 2x 7x 7 = 392
Therefore, the value for common factors is 392.
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 = 276152981591872/(1x392)
LCM = 276152981591872/392
LCM = 704471891816
Thus, we can understand that the LCM of 661,938,952,686,682 is 704471891816.
