Given numbers are 421,143,314,471

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

The LCM of 421,143,314,471 is 56711226.

Find LCM of 421,143,314,471 with Prime Factorization

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

157 x 421 x 143 x 2 x 3 = 56711226

Therefore, the lowest common multiple of 421,143,314,471 is 56711226.

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.

421 x 143 x 314 x 471 = 8903662482

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.

421 : 1, 421

143 : 1, 11, 13, 143

314 : 1, 2, 157, 314

471 : 1, 3, 157, 471

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,143,314,471, is 1.

Now, the common factors can be found like this.

421:421

143:11x 13

314:2x 157

471:3x 157

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

157 = 157

Therefore, the value for common factors is 157.

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 = 8903662482/(1x157)

LCM = 8903662482/157

LCM = 56711226

Thus, we can understand that the LCM of 421,143,314,471 is 56711226.
