Given numbers are 340,336,989,661

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

The LCM of 340,336,989,661 is 18670500240.

Find LCM of 340,336,989,661 with Prime Factorization

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

2 x 2 x 85 x 84 x 989 x 661 = 18670500240

Therefore, the lowest common multiple of 340,336,989,661 is 18670500240.

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.

340 x 336 x 989 x 661 = 74682000960

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.

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336

989 : 1, 23, 43, 989

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 340,336,989,661, is 1.

Now, the common factors can be found like this.

340:2x 2x 5x 17

336:2x 2x 2x 2x 3x 7

989:23x 43

661:661

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 74682000960/(1x4)

LCM = 74682000960/4

LCM = 18670500240

Thus, we can understand that the LCM of 340,336,989,661 is 18670500240.
