Given numbers are 958,668,210,776,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 958,668,210,776,686 is 319373652360.
Find LCM of 958,668,210,776,686 with Prime Factorization
| 2 | 958, 668, 210, 776, 686 |
| 2 | 479, 334, 105, 388, 343 |
| 7 | 479, 167, 105, 194, 343 |
| 479, 167, 15, 194, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 479 x 167 x 15 x 194 x 49 = 319373652360
Therefore, the lowest common multiple of 958,668,210,776,686 is 319373652360.
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 668 x 210 x 776 x 686 = 71539698128640
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
668 : 1, 2, 4, 167, 334, 668
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
776 : 1, 2, 4, 8, 97, 194, 388, 776
686 : 1, 2, 7, 14, 49, 98, 343, 686
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 958,668,210,776,686, is 2.
Now, the common factors can be found like this.
958:2x 479
668:2x 2x 167
210:2x 3x 5x 7
776:2x 2x 2x 97
686:2x 7x 7x 7
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 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 71539698128640/(2x112)
LCM = 71539698128640/224
LCM = 319373652360
Thus, we can understand that the LCM of 958,668,210,776,686 is 319373652360.
