Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 7 x 1 x 4 x 3 x 13 x 71 = 65126880
Therefore, the lowest common multiple of 392,480,441,780,426 is 65126880.
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.
392 x 480 x 441 x 780 x 426 = 27572115916800
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
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
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
426 : 1, 2, 3, 6, 71, 142, 213, 426
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,480,441,780,426, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
480:2x 2x 2x 2x 2x 3x 5
441:3x 3x 7x 7
780:2x 2x 3x 5x 13
426:2x 3x 71
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 3x 3x 3x 5x 7x 7 = 423360
Therefore, the value for common factors is 423360.
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 = 27572115916800/(1x423360)
LCM = 27572115916800/423360
LCM = 65126880
Thus, we can understand that the LCM of 392,480,441,780,426 is 65126880.
