Given numbers are 668,840,338,146

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

The LCM of 668,840,338,146 is 1730634360.

Find LCM of 668,840,338,146 with Prime Factorization

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

2 x 2 x 167 x 210 x 169 x 73 = 1730634360

Therefore, the lowest common multiple of 668,840,338,146 is 1730634360.

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.

668 x 840 x 338 x 146 = 27690149760

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.

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

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

338 : 1, 2, 13, 26, 169, 338

146 : 1, 2, 73, 146

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,840,338,146, is 2.

Now, the common factors can be found like this.

668:2x 2x 167

840:2x 2x 2x 3x 5x 7

338:2x 13x 13

146:2x 73

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 2 = 8

Therefore, the value for common factors is 8.

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 = 27690149760/(2x8)

LCM = 27690149760/16

LCM = 1730634360

Thus, we can understand that the LCM of 668,840,338,146 is 1730634360.
