| 43 | 301, 5, 361, 53, 43 |
| 7, 5, 361, 53, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 43 x 7 x 5 x 361 x 53 x 1 = 4146503760
Therefore, the lowest common multiple of 903,720,361,477,688 is 4146503760.
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.
903 x 720 x 361 x 477 x 688 = 77025453845760
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.
903 : 1, 3, 7, 21, 43, 129, 301, 903
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
361 : 1, 19, 361
477 : 1, 3, 9, 53, 159, 477
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 903,720,361,477,688, is 1.
Now, the common factors can be found like this.
903:3x 7x 43
720:2x 2x 2x 2x 3x 3x 5
361:19x 19
477:3x 3x 53
688:2x 2x 2x 2x 43
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 3x 3x 3x 43 = 18576
Therefore, the value for common factors is 18576.
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 = 77025453845760/(1x18576)
LCM = 77025453845760/18576
LCM = 4146503760
Thus, we can understand that the LCM of 903,720,361,477,688 is 4146503760.
