Given numbers are 756,682,139,938,287
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 756,682,139,938,287 is 98435020068.
Find LCM of 756,682,139,938,287 with Prime Factorization
| 2 | 756, 682, 139, 938, 287 |
| 7 | 378, 341, 139, 469, 287 |
| 54, 341, 139, 67, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 54 x 341 x 139 x 67 x 41 = 98435020068
Therefore, the lowest common multiple of 756,682,139,938,287 is 98435020068.
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.
756 x 682 x 139 x 938 x 287 = 19293263933328
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.
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
682 : 1, 2, 11, 22, 31, 62, 341, 682
139 : 1, 139
938 : 1, 2, 7, 14, 67, 134, 469, 938
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,682,139,938,287, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
682:2x 11x 31
139:139
938:2x 7x 67
287:7x 41
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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 19293263933328/(1x196)
LCM = 19293263933328/196
LCM = 98435020068
Thus, we can understand that the LCM of 756,682,139,938,287 is 98435020068.
