Calculate the LCM of 717,817,428,665

Given numbers are 717,817,428,665

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

The LCM of 717,817,428,665 is 8775119220.

Find LCM of 717,817,428,665 with Prime Factorization


19 717, 817, 428, 665
717, 43, 428, 35

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

19 x 717 x 43 x 428 x 35 = 8775119220

Therefore, the lowest common multiple of 717,817,428,665 is 8775119220.

LCM Formula to Find Lowest Common Multiple of 717,817,428,665

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.

717 x 817 x 428 x 665 = 166727265180

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.

717 : 1, 3, 239, 717

817 : 1, 19, 43, 817

428 : 1, 2, 4, 107, 214, 428

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 717,817,428,665, is 1.

Now, the common factors can be found like this.

717:3x 239

817:19x 43

428:2x 2x 107

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.

19 = 19

Therefore, the value for common factors is 19.

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 = 166727265180/(1x19)

LCM = 166727265180/19

LCM = 8775119220

Thus, we can understand that the LCM of 717,817,428,665 is 8775119220.
