Given numbers are 630,682,868,438

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

The LCM of 630,682,868,438 is 31365180.

Find LCM of 630,682,868,438 with Prime Factorization

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

2 x 3 x 7 x 31 x 15 x 11 x 2 x 73 = 31365180

Therefore, the lowest common multiple of 630,682,868,438 is 31365180.

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.

630 x 682 x 868 x 438 = 163349857440

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.

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

682 : 1, 2, 11, 22, 31, 62, 341, 682

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

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 630,682,868,438, is 2.

Now, the common factors can be found like this.

630:2x 3x 3x 5x 7

682:2x 11x 31

868:2x 2x 7x 31

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 2x 3x 7x 31 = 2604

Therefore, the value for common factors is 2604.

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 = 163349857440/(2x2604)

LCM = 163349857440/5208

LCM = 31365180

Thus, we can understand that the LCM of 630,682,868,438 is 31365180.
