Given numbers are 766,938,128,287,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 766,938,128,287,121 is 114064582016.
Find LCM of 766,938,128,287,121 with Prime Factorization
| 2 | 766, 938, 128, 287, 121 |
| 7 | 383, 469, 64, 287, 121 |
| 383, 67, 64, 41, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 383 x 67 x 64 x 41 x 121 = 114064582016
Therefore, the lowest common multiple of 766,938,128,287,121 is 114064582016.
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.
766 x 938 x 128 x 287 x 121 = 3193808296448
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.
766 : 1, 2, 383, 766
938 : 1, 2, 7, 14, 67, 134, 469, 938
128 : 1, 2, 4, 8, 16, 32, 64, 128
287 : 1, 7, 41, 287
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 766,938,128,287,121, is 1.
Now, the common factors can be found like this.
766:2x 383
938:2x 7x 67
128:2x 2x 2x 2x 2x 2x 2
287:7x 41
121:11x 11
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 7 = 28
Therefore, the value for common factors is 28.
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 = 3193808296448/(1x28)
LCM = 3193808296448/28
LCM = 114064582016
Thus, we can understand that the LCM of 766,938,128,287,121 is 114064582016.
