Given numbers are 128,698,680,216,202

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

The LCM of 128,698,680,216,202 is 10354746240.

Find LCM of 128,698,680,216,202 with Prime Factorization

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

2 x 2 x 2 x 16 x 349 x 85 x 27 x 101 = 10354746240

Therefore, the lowest common multiple of 128,698,680,216,202 is 10354746240.

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.

128 x 698 x 680 x 216 x 202 = 2650815037440

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

698 : 1, 2, 349, 698

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216

202 : 1, 2, 101, 202

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,698,680,216,202, is 2.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

698:2x 349

680:2x 2x 2x 5x 17

216:2x 2x 2x 3x 3x 3

202:2x 101

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 2 = 128

Therefore, the value for common factors is 128.

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 = 2650815037440/(2x128)

LCM = 2650815037440/256

LCM = 10354746240

Thus, we can understand that the LCM of 128,698,680,216,202 is 10354746240.
