Given numbers are 658,434,578,887,798
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 658,434,578,887,798 is 298046417298.
Find LCM of 658,434,578,887,798 with Prime Factorization
| 2 | 658, 434, 578, 887, 798 |
| 7 | 329, 217, 289, 887, 399 |
| 47, 31, 289, 887, 57 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 47 x 31 x 289 x 887 x 57 = 298046417298
Therefore, the lowest common multiple of 658,434,578,887,798 is 298046417298.
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.
658 x 434 x 578 x 887 x 798 = 116834195580816
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.
658 : 1, 2, 7, 14, 47, 94, 329, 658
434 : 1, 2, 7, 14, 31, 62, 217, 434
578 : 1, 2, 17, 34, 289, 578
887 : 1, 887
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,434,578,887,798, is 1.
Now, the common factors can be found like this.
658:2x 7x 47
434:2x 7x 31
578:2x 17x 17
887:887
798:2x 3x 7x 19
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 7x 7 = 392
Therefore, the value for common factors is 392.
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 = 116834195580816/(1x392)
LCM = 116834195580816/392
LCM = 298046417298
Thus, we can understand that the LCM of 658,434,578,887,798 is 298046417298.
