Given numbers are 426,631,871,644

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

The LCM of 426,631,871,644 is 75389868372.

Find LCM of 426,631,871,644 with Prime Factorization

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

2 x 213 x 631 x 871 x 322 = 75389868372

Therefore, the lowest common multiple of 426,631,871,644 is 75389868372.

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.

426 x 631 x 871 x 644 = 150779736744

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.

426 : 1, 2, 3, 6, 71, 142, 213, 426

631 : 1, 631

871 : 1, 13, 67, 871

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,631,871,644, is 1.

Now, the common factors can be found like this.

426:2x 3x 71

631:631

871:13x 67

644:2x 2x 7x 23

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

2 = 2

Therefore, the value for common factors is 2.

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 = 150779736744/(1x2)

LCM = 150779736744/2

LCM = 75389868372

Thus, we can understand that the LCM of 426,631,871,644 is 75389868372.
