Given numbers are 632,155,868,279
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 632,155,868,279 is 6171480.
Find LCM of 632,155,868,279 with Prime Factorization
| 2 | 632, 155, 868, 279 |
| 2 | 316, 155, 434, 279 |
| 31 | 158, 155, 217, 279 |
| 158, 5, 7, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 31 x 158 x 5 x 7 x 9 = 6171480
Therefore, the lowest common multiple of 632,155,868,279 is 6171480.
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.
632 x 155 x 868 x 279 = 23723169120
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.
632 : 1, 2, 4, 8, 79, 158, 316, 632
155 : 1, 5, 31, 155
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
279 : 1, 3, 9, 31, 93, 279
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 632,155,868,279, is 1.
Now, the common factors can be found like this.
632:2x 2x 2x 79
155:5x 31
868:2x 2x 7x 31
279:3x 3x 31
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 31x 31 = 3844
Therefore, the value for common factors is 3844.
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 = 23723169120/(1x3844)
LCM = 23723169120/3844
LCM = 6171480
Thus, we can understand that the LCM of 632,155,868,279 is 6171480.
