Given numbers are 210,278,314,431

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

The LCM of 210,278,314,431 is 1975199730.

Find LCM of 210,278,314,431 with Prime Factorization

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

2 x 105 x 139 x 157 x 431 = 1975199730

Therefore, the lowest common multiple of 210,278,314,431 is 1975199730.

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.

210 x 278 x 314 x 431 = 7900798920

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.

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

278 : 1, 2, 139, 278

314 : 1, 2, 157, 314

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,278,314,431, is 1.

Now, the common factors can be found like this.

210:2x 3x 5x 7

278:2x 139

314:2x 157

431:431

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 = 7900798920/(1x4)

LCM = 7900798920/4

LCM = 1975199730

Thus, we can understand that the LCM of 210,278,314,431 is 1975199730.
