Given numbers are 520,668,746,540

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

The LCM of 520,668,746,540 is 874565640.

Find LCM of 520,668,746,540 with Prime Factorization

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

2 x 2 x 5 x 26 x 167 x 373 x 27 = 874565640

Therefore, the lowest common multiple of 520,668,746,540 is 874565640.

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.

520 x 668 x 746 x 540 = 139930502400

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.

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

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

746 : 1, 2, 373, 746

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,668,746,540, is 2.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

668:2x 2x 167

746:2x 373

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

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 5 = 80

Therefore, the value for common factors is 80.

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 = 139930502400/(2x80)

LCM = 139930502400/160

LCM = 874565640

Thus, we can understand that the LCM of 520,668,746,540 is 874565640.
