Given numbers are 690,402,824,689,104

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

The LCM of 690,402,824,689,104 is 13123217640.

Find LCM of 690,402,824,689,104 with Prime Factorization

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

2 x 2 x 2 x 3 x 13 x 115 x 67 x 103 x 53 x 1 = 13123217640

Therefore, the lowest common multiple of 690,402,824,689,104 is 13123217640.

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.

690 x 402 x 824 x 689 x 104 = 16377775614720

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

402 : 1, 2, 3, 6, 67, 134, 201, 402

824 : 1, 2, 4, 8, 103, 206, 412, 824

689 : 1, 13, 53, 689

104 : 1, 2, 4, 8, 13, 26, 52, 104

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,402,824,689,104, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

402:2x 3x 67

824:2x 2x 2x 103

689:13x 53

104:2x 2x 2x 13

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 13 = 1248

Therefore, the value for common factors is 1248.

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 = 16377775614720/(1x1248)

LCM = 16377775614720/1248

LCM = 13123217640

Thus, we can understand that the LCM of 690,402,824,689,104 is 13123217640.
