Calculate the LCM of 643,377,448,746

Given numbers are 643,377,448,746

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

The LCM of 643,377,448,746 is 40507847744.

Find LCM of 643,377,448,746 with Prime Factorization


2 643, 377, 448, 746
643, 377, 224, 373

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

2 x 643 x 377 x 224 x 373 = 40507847744

Therefore, the lowest common multiple of 643,377,448,746 is 40507847744.

LCM Formula to Find Lowest Common Multiple of 643,377,448,746

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.

643 x 377 x 448 x 746 = 81015695488

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.

643 : 1, 643

377 : 1, 13, 29, 377

448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448

746 : 1, 2, 373, 746

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,377,448,746, is 1.

Now, the common factors can be found like this.

643:643

377:13x 29

448:2x 2x 2x 2x 2x 2x 7

746:2x 373

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 = 81015695488/(1x2)

LCM = 81015695488/2

LCM = 40507847744

Thus, we can understand that the LCM of 643,377,448,746 is 40507847744.
