The LCM of 468,641,646,605 is 58622155020.

Find LCM of 468,641,646,605 with Prime Factorization


2 468, 641, 646, 605
234, 641, 323, 605

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

2 x 234 x 641 x 323 x 605 = 58622155020

Therefore, the lowest common multiple of 468,641,646,605 is 58622155020.

LCM Formula to Find Lowest Common Multiple of 468,641,646,605

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.

468 x 641 x 646 x 605 = 117244310040

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.

468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468

641 : 1, 641

646 : 1, 2, 17, 19, 34, 38, 323, 646

605 : 1, 5, 11, 55, 121, 605

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 468,641,646,605, is 1.

Now, the common factors can be found like this.

468:2x 2x 3x 3x 13

641:641

646:2x 17x 19

605:5x 11x 11

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 = 117244310040/(1x2)

LCM = 117244310040/2

LCM = 58622155020

Thus, we can understand that the LCM of 468,641,646,605 is 58622155020.
