Calculate the LCM of 622,215,572,940

Given numbers are 622,215,572,940

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

The LCM of 622,215,572,940 is 1797598660.

Find LCM of 622,215,572,940 with Prime Factorization


2 622, 215, 572, 940
2 311, 215, 286, 470
5 311, 215, 143, 235
311, 43, 143, 47

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

2 x 2 x 5 x 311 x 43 x 143 x 47 = 1797598660

Therefore, the lowest common multiple of 622,215,572,940 is 1797598660.

LCM Formula to Find Lowest Common Multiple of 622,215,572,940

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.

622 x 215 x 572 x 940 = 71903946400

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.

622 : 1, 2, 311, 622

215 : 1, 5, 43, 215

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 622,215,572,940, is 1.

Now, the common factors can be found like this.

622:2x 311

215:5x 43

572:2x 2x 11x 13

940:2x 2x 5x 47

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 5 = 40

Therefore, the value for common factors is 40.

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 = 71903946400/(1x40)

LCM = 71903946400/40

LCM = 1797598660

Thus, we can understand that the LCM of 622,215,572,940 is 1797598660.
