Find LCM of 748,943,984,782 with Prime Factorization
| 2 | 748, 943, 984, 782 |
| 2 | 374, 943, 492, 391 |
| 17 | 187, 943, 246, 391 |
| 23 | 11, 943, 246, 23 |
| 41 | 11, 41, 246, 1 |
| 11, 1, 6, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 23 x 41 x 11 x 1 x 6 x 1 = 4232184
Therefore, the lowest common multiple of 748,943,984,782 is 4232184.
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.
748 x 943 x 984 x 782 = 542769133632
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.
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
943 : 1, 23, 41, 943
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,943,984,782, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
943:23x 41
984:2x 2x 2x 3x 41
782:2x 17x 23
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 17x 23x 41 = 128248
Therefore, the value for common factors is 128248.
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 = 542769133632/(1x128248)
LCM = 542769133632/128248
LCM = 4232184
Thus, we can understand that the LCM of 748,943,984,782 is 4232184.
