Calculate the LCM of 662,645,881,665

Given numbers are 662,645,881,665

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

The LCM of 662,645,881,665 is 50031699270.

Find LCM of 662,645,881,665 with Prime Factorization


5 662, 645, 881, 665
662, 129, 881, 133

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

5 x 662 x 129 x 881 x 133 = 50031699270

Therefore, the lowest common multiple of 662,645,881,665 is 50031699270.

LCM Formula to Find Lowest Common Multiple of 662,645,881,665

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.

662 x 645 x 881 x 665 = 250158496350

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.

662 : 1, 2, 331, 662

645 : 1, 3, 5, 15, 43, 129, 215, 645

881 : 1, 881

665 : 1, 5, 7, 19, 35, 95, 133, 665

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,645,881,665, is 1.

Now, the common factors can be found like this.

662:2x 331

645:3x 5x 43

881:881

665:5x 7x 19

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

5 = 5

Therefore, the value for common factors is 5.

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 = 250158496350/(1x5)

LCM = 250158496350/5

LCM = 50031699270

Thus, we can understand that the LCM of 662,645,881,665 is 50031699270.
