Given numbers are 668,700,276,720,905

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

The LCM of 668,700,276,720,905 is 17519569200.

Find LCM of 668,700,276,720,905 with Prime Factorization

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

2 x 2 x 3 x 5 x 167 x 35 x 23 x 12 x 181 = 17519569200

Therefore, the lowest common multiple of 668,700,276,720,905 is 17519569200.

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.

668 x 700 x 276 x 720 x 905 = 84093932160000

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.

668 : 1, 2, 4, 167, 334, 668

700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700

276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

905 : 1, 5, 181, 905

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,700,276,720,905, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

700:2x 2x 5x 5x 7

276:2x 2x 3x 23

720:2x 2x 2x 2x 3x 3x 5

905:5x 181

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 2x 3x 5x 5 = 4800

Therefore, the value for common factors is 4800.

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 = 84093932160000/(1x4800)

LCM = 84093932160000/4800

LCM = 17519569200

Thus, we can understand that the LCM of 668,700,276,720,905 is 17519569200.
