Given numbers are 942,158,640,290,317
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 942,158,640,290,317 is 218919895680.
Find LCM of 942,158,640,290,317 with Prime Factorization
| 2 | 942, 158, 640, 290, 317 |
| 5 | 471, 79, 320, 145, 317 |
| 471, 79, 64, 29, 317 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 471 x 79 x 64 x 29 x 317 = 218919895680
Therefore, the lowest common multiple of 942,158,640,290,317 is 218919895680.
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.
942 x 158 x 640 x 290 x 317 = 8756795827200
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.
942 : 1, 2, 3, 6, 157, 314, 471, 942
158 : 1, 2, 79, 158
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
290 : 1, 2, 5, 10, 29, 58, 145, 290
317 : 1, 317
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,158,640,290,317, is 1.
Now, the common factors can be found like this.
942:2x 3x 157
158:2x 79
640:2x 2x 2x 2x 2x 2x 2x 5
290:2x 5x 29
317:317
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 = 8756795827200/(1x40)
LCM = 8756795827200/40
LCM = 218919895680
Thus, we can understand that the LCM of 942,158,640,290,317 is 218919895680.
