Given numbers are 724,226,561,421

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

The LCM of 724,226,561,421 is 19322439972.

Find LCM of 724,226,561,421 with Prime Factorization

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

2 x 362 x 113 x 561 x 421 = 19322439972

Therefore, the lowest common multiple of 724,226,561,421 is 19322439972.

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.

724 x 226 x 561 x 421 = 38644879944

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.

724 : 1, 2, 4, 181, 362, 724

226 : 1, 2, 113, 226

561 : 1, 3, 11, 17, 33, 51, 187, 561

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,226,561,421, is 1.

Now, the common factors can be found like this.

724:2x 2x 181

226:2x 113

561:3x 11x 17

421:421

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

2 = 2

Therefore, the value for common factors is 2.

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 = 38644879944/(1x2)

LCM = 38644879944/2

LCM = 19322439972

Thus, we can understand that the LCM of 724,226,561,421 is 19322439972.
