Given numbers are 670,654,336,436,257
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 670,654,336,436,257 is 3153143280.
Find LCM of 670,654,336,436,257 with Prime Factorization
| 2 | 670, 654, 336, 436, 257 |
| 2 | 335, 327, 168, 218, 257 |
| 3 | 335, 327, 84, 109, 257 |
| 109 | 335, 109, 28, 109, 257 |
| 335, 1, 28, 1, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 109 x 335 x 1 x 28 x 1 x 257 = 3153143280
Therefore, the lowest common multiple of 670,654,336,436,257 is 3153143280.
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.
670 x 654 x 336 x 436 x 257 = 16497245640960
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.
670 : 1, 2, 5, 10, 67, 134, 335, 670
654 : 1, 2, 3, 6, 109, 218, 327, 654
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
436 : 1, 2, 4, 109, 218, 436
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,654,336,436,257, is 1.
Now, the common factors can be found like this.
670:2x 5x 67
654:2x 3x 109
336:2x 2x 2x 2x 3x 7
436:2x 2x 109
257:257
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 2x 3x 109 = 5232
Therefore, the value for common factors is 5232.
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 = 16497245640960/(1x5232)
LCM = 16497245640960/5232
LCM = 3153143280
Thus, we can understand that the LCM of 670,654,336,436,257 is 3153143280.
