Calculate the LCM of 325,612,420,485

Given numbers are 325,612,420,485

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

The LCM of 325,612,420,485 is 135053100.

Find LCM of 325,612,420,485 with Prime Factorization


2 325, 612, 420, 485
2 325, 306, 210, 485
3 325, 153, 105, 485
5 325, 51, 35, 485
65, 51, 7, 97

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

2 x 2 x 3 x 5 x 65 x 51 x 7 x 97 = 135053100

Therefore, the lowest common multiple of 325,612,420,485 is 135053100.

LCM Formula to Find Lowest Common Multiple of 325,612,420,485

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.

325 x 612 x 420 x 485 = 40515930000

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.

325 : 1, 5, 13, 25, 65, 325

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

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

485 : 1, 5, 97, 485

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 325,612,420,485, is 1.

Now, the common factors can be found like this.

325:5x 5x 13

612:2x 2x 3x 3x 17

420:2x 2x 3x 5x 7

485:5x 97

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 5x 5 = 300

Therefore, the value for common factors is 300.

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 = 40515930000/(1x300)

LCM = 40515930000/300

LCM = 135053100

Thus, we can understand that the LCM of 325,612,420,485 is 135053100.
