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

2 x 2 x 2 x 5 x 7 x 797 x 14 x 3 x 55 x 151 = 77840439600

Therefore, the lowest common multiple of 797,784,840,275,755 is 77840439600.

LCM Formula to Find Lowest Common Multiple of 797,784,840,275,755

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.

797 x 784 x 840 x 275 x 755 = 108976615440000

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.

797 : 1, 797

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

275 : 1, 5, 11, 25, 55, 275

755 : 1, 5, 151, 755

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 797,784,840,275,755, is 1.

Now, the common factors can be found like this.

797:797

784:2x 2x 2x 2x 7x 7

840:2x 2x 2x 3x 5x 7

275:5x 5x 11

755:5x 151

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 5x 5x 7 = 1400

Therefore, the value for common factors is 1400.

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 = 108976615440000/(1x1400)

LCM = 108976615440000/1400

LCM = 77840439600

Thus, we can understand that the LCM of 797,784,840,275,755 is 77840439600.
