Given numbers are 686,622,106,438

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

The LCM of 686,622,106,438 is 2476307022.

Find LCM of 686,622,106,438 with Prime Factorization

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

2 x 343 x 311 x 53 x 219 = 2476307022

Therefore, the lowest common multiple of 686,622,106,438 is 2476307022.

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.

686 x 622 x 106 x 438 = 19810456176

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.

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

622 : 1, 2, 311, 622

106 : 1, 2, 53, 106

438 : 1, 2, 3, 6, 73, 146, 219, 438

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,622,106,438, is 2.

Now, the common factors can be found like this.

686:2x 7x 7x 7

622:2x 311

106:2x 53

438:2x 3x 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 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 = 19810456176/(2x4)

LCM = 19810456176/8

LCM = 2476307022

Thus, we can understand that the LCM of 686,622,106,438 is 2476307022.
