Given numbers are 840,832,807,655

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

The LCM of 840,832,807,655 is 3078479040.

Find LCM of 840,832,807,655 with Prime Factorization

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

2 x 2 x 2 x 3 x 5 x 7 x 104 x 269 x 131 = 3078479040

Therefore, the lowest common multiple of 840,832,807,655 is 3078479040.

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.

840 x 832 x 807 x 655 = 369417484800

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.

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

832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832

807 : 1, 3, 269, 807

655 : 1, 5, 131, 655

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,832,807,655, is 1.

Now, the common factors can be found like this.

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

832:2x 2x 2x 2x 2x 2x 13

807:3x 269

655:5x 131

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 3x 5 = 120

Therefore, the value for common factors is 120.

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 = 369417484800/(1x120)

LCM = 369417484800/120

LCM = 3078479040

Thus, we can understand that the LCM of 840,832,807,655 is 3078479040.
