Given numbers are 958,778,850,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 958,778,850,680 is 633525400.
Find LCM of 958,778,850,680 with Prime Factorization
| 2 | 958, 778, 850, 680 |
| 5 | 479, 389, 425, 340 |
| 17 | 479, 389, 85, 68 |
| 479, 389, 5, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 479 x 389 x 5 x 4 = 633525400
Therefore, the lowest common multiple of 958,778,850,680 is 633525400.
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.
958 x 778 x 850 x 680 = 430797272000
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.
958 : 1, 2, 479, 958
778 : 1, 2, 389, 778
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 958,778,850,680, is 2.
Now, the common factors can be found like this.
958:2x 479
778:2x 389
850:2x 5x 5x 17
680:2x 2x 2x 5x 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 5x 17 = 340
Therefore, the value for common factors is 340.
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 = 430797272000/(2x340)
LCM = 430797272000/680
LCM = 633525400
Thus, we can understand that the LCM of 958,778,850,680 is 633525400.
