Given numbers are 623,894,612,972
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 623,894,612,972 is 1533873348.
Find LCM of 623,894,612,972 with Prime Factorization
| 2 | 623, 894, 612, 972 |
| 2 | 623, 447, 306, 486 |
| 3 | 623, 447, 153, 243 |
| 3 | 623, 149, 51, 81 |
| 623, 149, 17, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 623 x 149 x 17 x 27 = 1533873348
Therefore, the lowest common multiple of 623,894,612,972 is 1533873348.
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.
623 x 894 x 612 x 972 = 331316643168
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.
623 : 1, 7, 89, 623
894 : 1, 2, 3, 6, 149, 298, 447, 894
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,894,612,972, is 1.
Now, the common factors can be found like this.
623:7x 89
894:2x 3x 149
612:2x 2x 3x 3x 17
972:2x 2x 3x 3x 3x 3x 3
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 331316643168/(1x216)
LCM = 331316643168/216
LCM = 1533873348
Thus, we can understand that the LCM of 623,894,612,972 is 1533873348.
