Find LCM of 245,357,136,620,271 with Prime Factorization
| 2 | 245, 357, 136, 620, 271 |
| 2 | 245, 357, 68, 310, 271 |
| 5 | 245, 357, 34, 155, 271 |
| 7 | 49, 357, 34, 31, 271 |
| 17 | 7, 51, 34, 31, 271 |
| 7, 3, 2, 31, 271 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 17 x 7 x 3 x 2 x 31 x 271 = 839763960
Therefore, the lowest common multiple of 245,357,136,620,271 is 839763960.
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.
245 x 357 x 136 x 620 x 271 = 1998638224800
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.
245 : 1, 5, 7, 35, 49, 245
357 : 1, 3, 7, 17, 21, 51, 119, 357
136 : 1, 2, 4, 8, 17, 34, 68, 136
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
271 : 1, 271
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 245,357,136,620,271, is 1.
Now, the common factors can be found like this.
245:5x 7x 7
357:3x 7x 17
136:2x 2x 2x 17
620:2x 2x 5x 31
271:271
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 17 = 2380
Therefore, the value for common factors is 2380.
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 = 1998638224800/(1x2380)
LCM = 1998638224800/2380
LCM = 839763960
Thus, we can understand that the LCM of 245,357,136,620,271 is 839763960.
