Given numbers are 620,126,358,918,168
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,126,358,918,168 is 713157480.
Find LCM of 620,126,358,918,168 with Prime Factorization
| 2 | 620, 126, 358, 918, 168 |
| 2 | 310, 63, 179, 459, 84 |
| 3 | 155, 63, 179, 459, 42 |
| 3 | 155, 21, 179, 153, 14 |
| 7 | 155, 7, 179, 51, 14 |
| 155, 1, 179, 51, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 155 x 1 x 179 x 51 x 2 = 713157480
Therefore, the lowest common multiple of 620,126,358,918,168 is 713157480.
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.
620 x 126 x 358 x 918 x 168 = 4313176439040
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
358 : 1, 2, 179, 358
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,126,358,918,168, is 2.
Now, the common factors can be found like this.
620:2x 2x 5x 31
126:2x 3x 3x 7
358:2x 179
918:2x 3x 3x 3x 17
168:2x 2x 2x 3x 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 3x 3x 3x 7 = 3024
Therefore, the value for common factors is 3024.
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 = 4313176439040/(2x3024)
LCM = 4313176439040/6048
LCM = 713157480
Thus, we can understand that the LCM of 620,126,358,918,168 is 713157480.
