Given numbers are 7,538,538,387

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

The LCM of 7,538,538,387 is 1457442.

Find LCM of 7,538,538,387 with Prime Factorization

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

2 x 269 x 7 x 1 x 1 x 387 = 1457442

Therefore, the lowest common multiple of 7,538,538,387 is 1457442.

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.

7 x 538 x 538 x 387 = 784103796

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.

7 : 1, 7

538 : 1, 2, 269, 538

538 : 1, 2, 269, 538

387 : 1, 3, 9, 43, 129, 387

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,538,538,387, is 1.

Now, the common factors can be found like this.

7:7

538:2x 269

538:2x 269

387:3x 3x 43

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

2x 269 = 538

Therefore, the value for common factors is 538.

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 = 784103796/(1x538)

LCM = 784103796/538

LCM = 1457442

Thus, we can understand that the LCM of 7,538,538,387 is 1457442.
