Given numbers are 302,781,840,422

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

The LCM of 302,781,840,422 is 20902090440.

Find LCM of 302,781,840,422 with Prime Factorization

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

2 x 151 x 781 x 420 x 211 = 20902090440

Therefore, the lowest common multiple of 302,781,840,422 is 20902090440.

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.

302 x 781 x 840 x 422 = 83608361760

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.

302 : 1, 2, 151, 302

781 : 1, 11, 71, 781

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

422 : 1, 2, 211, 422

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 302,781,840,422, is 1.

Now, the common factors can be found like this.

302:2x 151

781:11x 71

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

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 2 = 4

Therefore, the value for common factors is 4.

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 = 83608361760/(1x4)

LCM = 83608361760/4

LCM = 20902090440

Thus, we can understand that the LCM of 302,781,840,422 is 20902090440.
