Given numbers are 840,988,386,764

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

The LCM of 840,988,386,764 is 7648335240.

Find LCM of 840,988,386,764 with Prime Factorization

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

2 x 2 x 210 x 247 x 193 x 191 = 7648335240

Therefore, the lowest common multiple of 840,988,386,764 is 7648335240.

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 988 x 386 x 764 = 244746727680

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

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

386 : 1, 2, 193, 386

764 : 1, 2, 4, 191, 382, 764

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,988,386,764, is 2.

Now, the common factors can be found like this.

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

988:2x 2x 13x 19

386:2x 193

764:2x 2x 191

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 2 = 16

Therefore, the value for common factors is 16.

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 = 244746727680/(2x16)

LCM = 244746727680/32

LCM = 7648335240

Thus, we can understand that the LCM of 840,988,386,764 is 7648335240.
