Given numbers are 658,697,287,209
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 658,697,287,209 is 95852834.
Find LCM of 658,697,287,209 with Prime Factorization
| 7 | 658, 697, 287, 209 |
| 41 | 94, 697, 41, 209 |
| 94, 17, 1, 209 |
Multiply the prime numbers at the bottom and the left side.
7 x 41 x 94 x 17 x 1 x 209 = 95852834
Therefore, the lowest common multiple of 658,697,287,209 is 95852834.
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 697 x 287 x 209 = 27509763358
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
697 : 1, 17, 41, 697
287 : 1, 7, 41, 287
209 : 1, 11, 19, 209
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,697,287,209, is 1.
Now, the common factors can be found like this.
658:2x 7x 47
697:17x 41
287:7x 41
209:11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 41 = 287
Therefore, the value for common factors is 287.
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 = 27509763358/(1x287)
LCM = 27509763358/287
LCM = 95852834
Thus, we can understand that the LCM of 658,697,287,209 is 95852834.
