Calculate the LCM of 612,905,221,200

Given numbers are 612,905,221,200

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

The LCM of 612,905,221,200 is 72001800.

Find LCM of 612,905,221,200 with Prime Factorization


2 612, 905, 221, 200
2 306, 905, 221, 100
5 153, 905, 221, 50
17 153, 181, 221, 10
9, 181, 13, 10

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

2 x 2 x 5 x 17 x 9 x 181 x 13 x 10 = 72001800

Therefore, the lowest common multiple of 612,905,221,200 is 72001800.

LCM Formula to Find Lowest Common Multiple of 612,905,221,200

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.

612 x 905 x 221 x 200 = 24480612000

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.

612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612

905 : 1, 5, 181, 905

221 : 1, 13, 17, 221

200 : 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,905,221,200, is 1.

Now, the common factors can be found like this.

612:2x 2x 3x 3x 17

905:5x 181

221:13x 17

200:2x 2x 2x 5x 5

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 5x 17 = 340

Therefore, the value for common factors is 340.

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 = 24480612000/(1x340)

LCM = 24480612000/340

LCM = 72001800

Thus, we can understand that the LCM of 612,905,221,200 is 72001800.
