Calculate the LCM of 709,709,440,781

Given numbers are 709,709,440,781

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

The LCM of 709,709,440,781 is 22149160.

Find LCM of 709,709,440,781 with Prime Factorization


11 709, 709, 440, 781
709 709, 709, 40, 71
1, 1, 40, 71

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

11 x 709 x 1 x 1 x 40 x 71 = 22149160

Therefore, the lowest common multiple of 709,709,440,781 is 22149160.

LCM Formula to Find Lowest Common Multiple of 709,709,440,781

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.

709 x 709 x 440 x 781 = 172741298840

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.

709 : 1, 709

709 : 1, 709

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 709,709,440,781, is 1.

Now, the common factors can be found like this.

709:709

709:709

440:2x 2x 2x 5x 11

781:11x 71

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

11x 709 = 7799

Therefore, the value for common factors is 7799.

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 = 172741298840/(1x7799)

LCM = 172741298840/7799

LCM = 22149160

Thus, we can understand that the LCM of 709,709,440,781 is 22149160.
