Given numbers are 641,533,646,558

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

The LCM of 641,533,646,558 is 61577486802.

Find LCM of 641,533,646,558 with Prime Factorization

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

2 x 641 x 533 x 323 x 279 = 61577486802

Therefore, the lowest common multiple of 641,533,646,558 is 61577486802.

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.

641 x 533 x 646 x 558 = 123154973604

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.

641 : 1, 641

533 : 1, 13, 41, 533

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

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,533,646,558, is 1.

Now, the common factors can be found like this.

641:641

533:13x 41

646:2x 17x 19

558:2x 3x 3x 31

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 = 123154973604/(1x2)

LCM = 123154973604/2

LCM = 61577486802

Thus, we can understand that the LCM of 641,533,646,558 is 61577486802.
