Given numbers are 449,641,478,641

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

The LCM of 449,641,478,641 is 137572702.

Find LCM of 449,641,478,641 with Prime Factorization

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

641 x 449 x 1 x 478 x 1 = 137572702

Therefore, the lowest common multiple of 449,641,478,641 is 137572702.

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.

449 x 641 x 478 x 641 = 88184101982

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.

449 : 1, 449

641 : 1, 641

478 : 1, 2, 239, 478

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,641,478,641, is 1.

Now, the common factors can be found like this.

449:449

641:641

478:2x 239

641:641

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

641 = 641

Therefore, the value for common factors is 641.

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 = 88184101982/(1x641)

LCM = 88184101982/641

LCM = 137572702

Thus, we can understand that the LCM of 449,641,478,641 is 137572702.
