Given numbers are 290,217,492,770,217
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 290,217,492,770,217 is 170288580.
Find LCM of 290,217,492,770,217 with Prime Factorization
| 2 | 290, 217, 492, 770, 217 |
| 5 | 145, 217, 246, 385, 217 |
| 7 | 29, 217, 246, 77, 217 |
| 31 | 29, 31, 246, 11, 31 |
| 29, 1, 246, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 31 x 29 x 1 x 246 x 11 x 1 = 170288580
Therefore, the lowest common multiple of 290,217,492,770,217 is 170288580.
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.
290 x 217 x 492 x 770 x 217 = 5173367060400
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.
290 : 1, 2, 5, 10, 29, 58, 145, 290
217 : 1, 7, 31, 217
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
217 : 1, 7, 31, 217
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,217,492,770,217, is 1.
Now, the common factors can be found like this.
290:2x 5x 29
217:7x 31
492:2x 2x 3x 41
770:2x 5x 7x 11
217:7x 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 5x 7x 7x 31 = 30380
Therefore, the value for common factors is 30380.
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 = 5173367060400/(1x30380)
LCM = 5173367060400/30380
LCM = 170288580
Thus, we can understand that the LCM of 290,217,492,770,217 is 170288580.
