Given numbers are 196,812,720,856

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 196,812,720,856 is 109473840.

Find LCM of 196,812,720,856 with Prime Factorization

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

2 x 2 x 2 x 7 x 7 x 29 x 90 x 107 = 109473840

Therefore, the lowest common multiple of 196,812,720,856 is 109473840.

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.

196 x 812 x 720 x 856 = 98088560640

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.

196 : 1, 2, 4, 7, 14, 28, 49, 98, 196

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

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

856 : 1, 2, 4, 8, 107, 214, 428, 856

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 196,812,720,856, is 4.

Now, the common factors can be found like this.

196:2x 2x 7x 7

812:2x 2x 7x 29

720:2x 2x 2x 2x 3x 3x 5

856:2x 2x 2x 107

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 7 = 224

Therefore, the value for common factors is 224.

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 = 98088560640/(4x224)

LCM = 98088560640/896

LCM = 109473840

Thus, we can understand that the LCM of 196,812,720,856 is 109473840.
