Given numbers are 632,180,861,868
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 632,180,861,868 is 253030680.
Find LCM of 632,180,861,868 with Prime Factorization
| 2 | 632, 180, 861, 868 |
| 2 | 316, 90, 861, 434 |
| 3 | 158, 45, 861, 217 |
| 7 | 158, 15, 287, 217 |
| 158, 15, 41, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 158 x 15 x 41 x 31 = 253030680
Therefore, the lowest common multiple of 632,180,861,868 is 253030680.
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 180 x 861 x 868 = 85018308480
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
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
861 : 1, 3, 7, 21, 41, 123, 287, 861
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 632,180,861,868, is 1.
Now, the common factors can be found like this.
632:2x 2x 2x 79
180:2x 2x 3x 3x 5
861:3x 7x 41
868:2x 2x 7x 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 2x 2x 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 85018308480/(1x336)
LCM = 85018308480/336
LCM = 253030680
Thus, we can understand that the LCM of 632,180,861,868 is 253030680.
