Given numbers are 858,572,478,580
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,572,478,580 is 59467980.
Find LCM of 858,572,478,580 with Prime Factorization
| 2 | 858, 572, 478, 580 |
| 2 | 429, 286, 239, 290 |
| 11 | 429, 143, 239, 145 |
| 13 | 39, 13, 239, 145 |
| 3, 1, 239, 145 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 13 x 3 x 1 x 239 x 145 = 59467980
Therefore, the lowest common multiple of 858,572,478,580 is 59467980.
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.
858 x 572 x 478 x 580 = 136062738240
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
478 : 1, 2, 239, 478
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,572,478,580, is 2.
Now, the common factors can be found like this.
858:2x 3x 11x 13
572:2x 2x 11x 13
478:2x 239
580:2x 2x 5x 29
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 11x 13 = 1144
Therefore, the value for common factors is 1144.
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 = 136062738240/(2x1144)
LCM = 136062738240/2288
LCM = 59467980
Thus, we can understand that the LCM of 858,572,478,580 is 59467980.
