Given numbers are 212,622,868,821

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

The LCM of 212,622,868,821 is 11746247324.

Find LCM of 212,622,868,821 with Prime Factorization

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

2 x 2 x 53 x 311 x 217 x 821 = 11746247324

Therefore, the lowest common multiple of 212,622,868,821 is 11746247324.

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.

212 x 622 x 868 x 821 = 93969978592

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.

212 : 1, 2, 4, 53, 106, 212

622 : 1, 2, 311, 622

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

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,622,868,821, is 1.

Now, the common factors can be found like this.

212:2x 2x 53

622:2x 311

868:2x 2x 7x 31

821:821

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 = 93969978592/(1x8)

LCM = 93969978592/8

LCM = 11746247324

Thus, we can understand that the LCM of 212,622,868,821 is 11746247324.
