Given numbers are 428,621,163,376

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

The LCM of 428,621,163,376 is 4072403736.

Find LCM of 428,621,163,376 with Prime Factorization

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

2 x 2 x 107 x 621 x 163 x 94 = 4072403736

Therefore, the lowest common multiple of 428,621,163,376 is 4072403736.

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.

428 x 621 x 163 x 376 = 16289614944

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.

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

621 : 1, 3, 9, 23, 27, 69, 207, 621

163 : 1, 163

376 : 1, 2, 4, 8, 47, 94, 188, 376

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,621,163,376, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

621:3x 3x 3x 23

163:163

376:2x 2x 2x 47

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 = 16289614944/(1x4)

LCM = 16289614944/4

LCM = 4072403736

Thus, we can understand that the LCM of 428,621,163,376 is 4072403736.
