Given numbers are 538,412,709,721

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

The LCM of 538,412,709,721 is 550039364.

Find LCM of 538,412,709,721 with Prime Factorization

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

2 x 103 x 269 x 2 x 709 x 7 = 550039364

Therefore, the lowest common multiple of 538,412,709,721 is 550039364.

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.

538 x 412 x 709 x 721 = 113308108984

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.

538 : 1, 2, 269, 538

412 : 1, 2, 4, 103, 206, 412

709 : 1, 709

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,412,709,721, is 1.

Now, the common factors can be found like this.

538:2x 269

412:2x 2x 103

709:709

721:7x 103

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

2x 103 = 206

Therefore, the value for common factors is 206.

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 = 113308108984/(1x206)

LCM = 113308108984/206

LCM = 550039364

Thus, we can understand that the LCM of 538,412,709,721 is 550039364.
