Given numbers are 840,374,208,234,681

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

The LCM of 840,374,208,234,681 is 2781258480.

Find LCM of 840,374,208,234,681 with Prime Factorization

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

2 x 2 x 2 x 3 x 13 x 35 x 187 x 2 x 3 x 227 = 2781258480

Therefore, the lowest common multiple of 840,374,208,234,681 is 2781258480.

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 374 x 208 x 234 x 681 = 10413031749120

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

374 : 1, 2, 11, 17, 22, 34, 187, 374

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234

681 : 1, 3, 227, 681

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,374,208,234,681, is 1.

Now, the common factors can be found like this.

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

374:2x 11x 17

208:2x 2x 2x 2x 13

234:2x 3x 3x 13

681:3x 227

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 3x 3x 13 = 3744

Therefore, the value for common factors is 3744.

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 = 10413031749120/(1x3744)

LCM = 10413031749120/3744

LCM = 2781258480

Thus, we can understand that the LCM of 840,374,208,234,681 is 2781258480.
