Given numbers are 127,428,685,321

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

The LCM of 127,428,685,321 is 111701580.

Find LCM of 127,428,685,321 with Prime Factorization

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

107 x 127 x 4 x 685 x 3 = 111701580

Therefore, the lowest common multiple of 127,428,685,321 is 111701580.

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.

127 x 428 x 685 x 321 = 11952069060

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.

127 : 1, 127

428 : 1, 2, 4, 107, 214, 428

685 : 1, 5, 137, 685

321 : 1, 3, 107, 321

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 127,428,685,321, is 1.

Now, the common factors can be found like this.

127:127

428:2x 2x 107

685:5x 137

321:3x 107

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

107 = 107

Therefore, the value for common factors is 107.

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 = 11952069060/(1x107)

LCM = 11952069060/107

LCM = 111701580

Thus, we can understand that the LCM of 127,428,685,321 is 111701580.
