Given numbers are 862,240,246,540,644

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

The LCM of 862,240,246,540,644 is 6145266960.

Find LCM of 862,240,246,540,644 with Prime Factorization

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

2 x 2 x 3 x 5 x 431 x 4 x 41 x 9 x 161 = 6145266960

Therefore, the lowest common multiple of 862,240,246,540,644 is 6145266960.

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.

862 x 240 x 246 x 540 x 644 = 17698368844800

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.

862 : 1, 2, 431, 862

240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240

246 : 1, 2, 3, 6, 41, 82, 123, 246

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,240,246,540,644, is 2.

Now, the common factors can be found like this.

862:2x 431

240:2x 2x 2x 2x 3x 5

246:2x 3x 41

540:2x 2x 3x 3x 3x 5

644:2x 2x 7x 23

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 2x 2x 2x 3x 3x 5 = 1440

Therefore, the value for common factors is 1440.

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 = 17698368844800/(2x1440)

LCM = 17698368844800/2880

LCM = 6145266960

Thus, we can understand that the LCM of 862,240,246,540,644 is 6145266960.
