Given numbers are 862,668,406,238
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 862,668,406,238 is 993570508.
Find LCM of 862,668,406,238 with Prime Factorization
| 2 | 862, 668, 406, 238 |
| 7 | 431, 334, 203, 119 |
| 431, 334, 29, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 431 x 334 x 29 x 17 = 993570508
Therefore, the lowest common multiple of 862,668,406,238 is 993570508.
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.
862 x 668 x 406 x 238 = 55639948448
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.
862 : 1, 2, 431, 862
668 : 1, 2, 4, 167, 334, 668
406 : 1, 2, 7, 14, 29, 58, 203, 406
238 : 1, 2, 7, 14, 17, 34, 119, 238
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,668,406,238, is 2.
Now, the common factors can be found like this.
862:2x 431
668:2x 2x 167
406:2x 7x 29
238:2x 7x 17
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 7 = 28
Therefore, the value for common factors is 28.
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 = 55639948448/(2x28)
LCM = 55639948448/56
LCM = 993570508
Thus, we can understand that the LCM of 862,668,406,238 is 993570508.
