Given numbers are 660,552,168,698

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

The LCM of 660,552,168,698 is 74169480.

Find LCM of 660,552,168,698 with Prime Factorization

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

2 x 2 x 2 x 3 x 55 x 23 x 7 x 349 = 74169480

Therefore, the lowest common multiple of 660,552,168,698 is 74169480.

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.

660 x 552 x 168 x 698 = 42721620480

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

698 : 1, 2, 349, 698

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,552,168,698, is 2.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

552:2x 2x 2x 3x 23

168:2x 2x 2x 3x 7

698:2x 349

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 3 = 288

Therefore, the value for common factors is 288.

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 = 42721620480/(2x288)

LCM = 42721620480/576

LCM = 74169480

Thus, we can understand that the LCM of 660,552,168,698 is 74169480.
