Find LCM of 984,390,689,460,743 with Prime Factorization
| 2 | 984, 390, 689, 460, 743 |
| 2 | 492, 195, 689, 230, 743 |
| 3 | 246, 195, 689, 115, 743 |
| 5 | 82, 65, 689, 115, 743 |
| 13 | 82, 13, 689, 23, 743 |
| 82, 1, 53, 23, 743 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 82 x 1 x 53 x 23 x 743 = 57929659320
Therefore, the lowest common multiple of 984,390,689,460,743 is 57929659320.
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.
984 x 390 x 689 x 460 x 743 = 90370268539200
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.
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
689 : 1, 13, 53, 689
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
743 : 1, 743
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 984,390,689,460,743, is 1.
Now, the common factors can be found like this.
984:2x 2x 2x 3x 41
390:2x 3x 5x 13
689:13x 53
460:2x 2x 5x 23
743:743
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 5x 13 = 1560
Therefore, the value for common factors is 1560.
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 = 90370268539200/(1x1560)
LCM = 90370268539200/1560
LCM = 57929659320
Thus, we can understand that the LCM of 984,390,689,460,743 is 57929659320.
