| 7 | 109, 14, 119, 1, 13 |
| 109, 2, 17, 1, 13 |
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 7 x 109 x 2 x 17 x 1 x 13 = 161878080
Therefore, the lowest common multiple of 654,448,119,480,390 is 161878080.
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.
654 x 448 x 119 x 480 x 390 = 6526924185600
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.
654 : 1, 2, 3, 6, 109, 218, 327, 654
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
119 : 1, 7, 17, 119
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
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,448,119,480,390, is 1.
Now, the common factors can be found like this.
654:2x 3x 109
448:2x 2x 2x 2x 2x 2x 7
119:7x 17
480:2x 2x 2x 2x 2x 3x 5
390:2x 3x 5x 13
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 3x 5x 7 = 40320
Therefore, the value for common factors is 40320.
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 = 6526924185600/(1x40320)
LCM = 6526924185600/40320
LCM = 161878080
Thus, we can understand that the LCM of 654,448,119,480,390 is 161878080.
