Given numbers are 668,700,679,299,840

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

The LCM of 668,700,679,299,840 is 20342704200.

Find LCM of 668,700,679,299,840 with Prime Factorization

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

2 x 2 x 5 x 7 x 167 x 5 x 97 x 299 x 6 = 20342704200

Therefore, the lowest common multiple of 668,700,679,299,840 is 20342704200.

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 679 x 299 x 840 = 79743400464000

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

679 : 1, 7, 97, 679

299 : 1, 13, 23, 299

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,700,679,299,840, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

700:2x 2x 5x 5x 7

679:7x 97

299:13x 23

840:2x 2x 2x 3x 5x 7

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 5x 7x 7 = 3920

Therefore, the value for common factors is 3920.

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 = 79743400464000/(1x3920)

LCM = 79743400464000/3920

LCM = 20342704200

Thus, we can understand that the LCM of 668,700,679,299,840 is 20342704200.
