Find LCM of 942,842,640,515,480 with Prime Factorization
| 2 | 942, 842, 640, 515, 480 |
| 2 | 471, 421, 320, 515, 240 |
| 2 | 471, 421, 160, 515, 120 |
| 2 | 471, 421, 80, 515, 60 |
| 2 | 471, 421, 40, 515, 30 |
| 3 | 471, 421, 20, 515, 15 |
| 5 | 157, 421, 20, 515, 5 |
| 157, 421, 4, 103, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 5 x 157 x 421 x 4 x 103 x 1 = 13071342720
Therefore, the lowest common multiple of 942,842,640,515,480 is 13071342720.
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.
942 x 842 x 640 x 515 x 480 = 125484890112000
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.
942 : 1, 2, 3, 6, 157, 314, 471, 942
842 : 1, 2, 421, 842
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
515 : 1, 5, 103, 515
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,842,640,515,480, is 1.
Now, the common factors can be found like this.
942:2x 3x 157
842:2x 421
640:2x 2x 2x 2x 2x 2x 2x 5
515:5x 103
480:2x 2x 2x 2x 2x 3x 5
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 2x 2x 2x 2x 3x 5x 5 = 9600
Therefore, the value for common factors is 9600.
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 = 125484890112000/(1x9600)
LCM = 125484890112000/9600
LCM = 13071342720
Thus, we can understand that the LCM of 942,842,640,515,480 is 13071342720.
