Given numbers are 322,217,152,742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 322,217,152,742 is 40207496.
Find LCM of 322,217,152,742 with Prime Factorization
| 2 | 322, 217, 152, 742 |
| 7 | 161, 217, 76, 371 |
| 23, 31, 76, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 31 x 76 x 53 = 40207496
Therefore, the lowest common multiple of 322,217,152,742 is 40207496.
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.
322 x 217 x 152 x 742 = 7880669216
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.
322 : 1, 2, 7, 14, 23, 46, 161, 322
217 : 1, 7, 31, 217
152 : 1, 2, 4, 8, 19, 38, 76, 152
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 322,217,152,742, is 1.
Now, the common factors can be found like this.
322:2x 7x 23
217:7x 31
152:2x 2x 2x 19
742:2x 7x 53
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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 7880669216/(1x196)
LCM = 7880669216/196
LCM = 40207496
Thus, we can understand that the LCM of 322,217,152,742 is 40207496.
