Given numbers are 421,318,406,710

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

The LCM of 421,318,406,710 is 9647918070.

Find LCM of 421,318,406,710 with Prime Factorization

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

2 x 421 x 159 x 203 x 355 = 9647918070

Therefore, the lowest common multiple of 421,318,406,710 is 9647918070.

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 318 x 406 x 710 = 38591672280

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

318 : 1, 2, 3, 6, 53, 106, 159, 318

406 : 1, 2, 7, 14, 29, 58, 203, 406

710 : 1, 2, 5, 10, 71, 142, 355, 710

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,318,406,710, is 1.

Now, the common factors can be found like this.

421:421

318:2x 3x 53

406:2x 7x 29

710:2x 5x 71

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 = 38591672280/(1x4)

LCM = 38591672280/4

LCM = 9647918070

Thus, we can understand that the LCM of 421,318,406,710 is 9647918070.
