Given numbers are 868,900,393,669

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

The LCM of 868,900,393,669 is 5705298900.

Find LCM of 868,900,393,669 with Prime Factorization

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

2 x 2 x 3 x 217 x 75 x 131 x 223 = 5705298900

Therefore, the lowest common multiple of 868,900,393,669 is 5705298900.

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.

868 x 900 x 393 x 669 = 205390760400

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.

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

393 : 1, 3, 131, 393

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,900,393,669, is 1.

Now, the common factors can be found like this.

868:2x 2x 7x 31

900:2x 2x 3x 3x 5x 5

393:3x 131

669:3x 223

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 3 = 36

Therefore, the value for common factors is 36.

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 = 205390760400/(1x36)

LCM = 205390760400/36

LCM = 5705298900

Thus, we can understand that the LCM of 868,900,393,669 is 5705298900.
