Given numbers are 646,121,558,528

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

The LCM of 646,121,558,528 is 174466512.

Find LCM of 646,121,558,528 with Prime Factorization

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

2 x 3 x 11 x 323 x 11 x 93 x 8 = 174466512

Therefore, the lowest common multiple of 646,121,558,528 is 174466512.

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.

646 x 121 x 558 x 528 = 23029579584

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.

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

121 : 1, 11, 121

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

528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,121,558,528, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

121:11x 11

558:2x 3x 3x 31

528:2x 2x 2x 2x 3x 11

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

2x 2x 3x 11 = 132

Therefore, the value for common factors is 132.

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 = 23029579584/(1x132)

LCM = 23029579584/132

LCM = 174466512

Thus, we can understand that the LCM of 646,121,558,528 is 174466512.
