Given numbers are 122,208,330,938,785
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 122,208,330,938,785 is 154152158160.
Find LCM of 122,208,330,938,785 with Prime Factorization
| 2 | 122, 208, 330, 938, 785 |
| 5 | 61, 104, 165, 469, 785 |
| 61, 104, 33, 469, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 61 x 104 x 33 x 469 x 157 = 154152158160
Therefore, the lowest common multiple of 122,208,330,938,785 is 154152158160.
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.
122 x 208 x 330 x 938 x 785 = 6166086326400
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.
122 : 1, 2, 61, 122
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
938 : 1, 2, 7, 14, 67, 134, 469, 938
785 : 1, 5, 157, 785
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,208,330,938,785, is 1.
Now, the common factors can be found like this.
122:2x 61
208:2x 2x 2x 2x 13
330:2x 3x 5x 11
938:2x 7x 67
785:5x 157
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 5 = 40
Therefore, the value for common factors is 40.
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 = 6166086326400/(1x40)
LCM = 6166086326400/40
LCM = 154152158160
Thus, we can understand that the LCM of 122,208,330,938,785 is 154152158160.
