Given numbers are 840,579,473,678,422

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

The LCM of 840,579,473,678,422 is 1828347046680.

Find LCM of 840,579,473,678,422 with Prime Factorization

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

2 x 3 x 140 x 193 x 473 x 113 x 211 = 1828347046680

Therefore, the lowest common multiple of 840,579,473,678,422 is 1828347046680.

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 579 x 473 x 678 x 422 = 65820493680480

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

579 : 1, 3, 193, 579

473 : 1, 11, 43, 473

678 : 1, 2, 3, 6, 113, 226, 339, 678

422 : 1, 2, 211, 422

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,579,473,678,422, is 1.

Now, the common factors can be found like this.

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

579:3x 193

473:11x 43

678:2x 3x 113

422:2x 211

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 65820493680480/(1x36)

LCM = 65820493680480/36

LCM = 1828347046680

Thus, we can understand that the LCM of 840,579,473,678,422 is 1828347046680.
