Given numbers are 644,603,473,412

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

The LCM of 644,603,473,412 is 18919146708.

Find LCM of 644,603,473,412 with Prime Factorization

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

2 x 2 x 161 x 603 x 473 x 103 = 18919146708

Therefore, the lowest common multiple of 644,603,473,412 is 18919146708.

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.

644 x 603 x 473 x 412 = 75676586832

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.

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

603 : 1, 3, 9, 67, 201, 603

473 : 1, 11, 43, 473

412 : 1, 2, 4, 103, 206, 412

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,603,473,412, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

603:3x 3x 67

473:11x 43

412:2x 2x 103

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 = 75676586832/(1x4)

LCM = 75676586832/4

LCM = 18919146708

Thus, we can understand that the LCM of 644,603,473,412 is 18919146708.
