The LCM of 705,794,428,560,738 is 412559446320.

Find LCM of 705,794,428,560,738 with Prime Factorization


2 705, 794, 428, 560, 738
2 705, 397, 214, 280, 369
3 705, 397, 107, 140, 369
5 235, 397, 107, 140, 123
47, 397, 107, 28, 123

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 3 x 5 x 47 x 397 x 107 x 28 x 123 = 412559446320

LCM Formula to Find Lowest Common Multiple of 705,794,428,560,738

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.

705 x 794 x 428 x 560 x 738 = 99014267116800

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.

705 : 1, 3, 5, 15, 47, 141, 235, 705

794 : 1, 2, 397, 794

428 : 1, 2, 4, 107, 214, 428

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,794,428,560,738, is 1.

Now, the common factors can be found like this.

705:3x 5x 47

794:2x 397

428:2x 2x 107

560:2x 2x 2x 2x 5x 7

738:2x 3x 3x 41

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 5 = 240

Therefore, the value for common factors is 240.

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 = 99014267116800/(1x240)

LCM = 99014267116800/240

LCM = 412559446320

Thus, we can understand that the LCM of 705,794,428,560,738 is 412559446320.
