Given numbers are 646,624,209,133

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

The LCM of 646,624,209,133 is 15519504.

Find LCM of 646,624,209,133 with Prime Factorization

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

2 x 19 x 17 x 312 x 11 x 7 = 15519504

Therefore, the lowest common multiple of 646,624,209,133 is 15519504.

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 624 x 209 x 133 = 11205081888

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

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

209 : 1, 11, 19, 209

133 : 1, 7, 19, 133

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,624,209,133, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

624:2x 2x 2x 2x 3x 13

209:11x 19

133:7x 19

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

2x 19x 19 = 722

Therefore, the value for common factors is 722.

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 = 11205081888/(1x722)

LCM = 11205081888/722

LCM = 15519504

Thus, we can understand that the LCM of 646,624,209,133 is 15519504.
