Given numbers are 391,214,840,202

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

The LCM of 391,214,840,202 is 3549451080.

Find LCM of 391,214,840,202 with Prime Factorization

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

2 x 391 x 107 x 420 x 101 = 3549451080

Therefore, the lowest common multiple of 391,214,840,202 is 3549451080.

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.

391 x 214 x 840 x 202 = 14197804320

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.

391 : 1, 17, 23, 391

214 : 1, 2, 107, 214

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

202 : 1, 2, 101, 202

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,214,840,202, is 1.

Now, the common factors can be found like this.

391:17x 23

214:2x 107

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

202:2x 101

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 = 14197804320/(1x4)

LCM = 14197804320/4

LCM = 3549451080

Thus, we can understand that the LCM of 391,214,840,202 is 3549451080.
