Given numbers are 743,834,612,972
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 743,834,612,972 is 1706549148.
Find LCM of 743,834,612,972 with Prime Factorization
| 2 | 743, 834, 612, 972 |
| 2 | 743, 417, 306, 486 |
| 3 | 743, 417, 153, 243 |
| 3 | 743, 139, 51, 81 |
| 743, 139, 17, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 743 x 139 x 17 x 27 = 1706549148
Therefore, the lowest common multiple of 743,834,612,972 is 1706549148.
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.
743 x 834 x 612 x 972 = 368614615968
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.
743 : 1, 743
834 : 1, 2, 3, 6, 139, 278, 417, 834
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 743,834,612,972, is 1.
Now, the common factors can be found like this.
743:743
834:2x 3x 139
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 = 368614615968/(1x216)
LCM = 368614615968/216
LCM = 1706549148
Thus, we can understand that the LCM of 743,834,612,972 is 1706549148.
