Given numbers are 228,770,176,994,686

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

The LCM of 228,770,176,994,686 is 1221546480.

Find LCM of 228,770,176,994,686 with Prime Factorization

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

2 x 2 x 7 x 11 x 57 x 5 x 4 x 71 x 49 = 1221546480

Therefore, the lowest common multiple of 228,770,176,994,686 is 1221546480.

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.

228 x 770 x 176 x 994 x 686 = 21069233687040

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.

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

994 : 1, 2, 7, 14, 71, 142, 497, 994

686 : 1, 2, 7, 14, 49, 98, 343, 686

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,770,176,994,686, is 2.

Now, the common factors can be found like this.

228:2x 2x 3x 19

770:2x 5x 7x 11

176:2x 2x 2x 2x 11

994:2x 7x 71

686:2x 7x 7x 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 7x 7x 11 = 8624

Therefore, the value for common factors is 8624.

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 = 21069233687040/(2x8624)

LCM = 21069233687040/17248

LCM = 1221546480

Thus, we can understand that the LCM of 228,770,176,994,686 is 1221546480.
