Given numbers are 428,126,643,914

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

The LCM of 428,126,643,914 is 7923398364.

Find LCM of 428,126,643,914 with Prime Factorization

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

2 x 214 x 63 x 643 x 457 = 7923398364

Therefore, the lowest common multiple of 428,126,643,914 is 7923398364.

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 126 x 643 x 914 = 31693593456

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

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

643 : 1, 643

914 : 1, 2, 457, 914

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,126,643,914, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

126:2x 3x 3x 7

643:643

914:2x 457

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 = 31693593456/(1x4)

LCM = 31693593456/4

LCM = 7923398364

Thus, we can understand that the LCM of 428,126,643,914 is 7923398364.
