Calculate the LCM of 717,856,471,894

Given numbers are 717,856,471,894

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

The LCM of 717,856,471,894 is 14357500536.

Find LCM of 717,856,471,894 with Prime Factorization


2 717, 856, 471, 894
3 717, 428, 471, 447
239, 428, 157, 149

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

2 x 3 x 239 x 428 x 157 x 149 = 14357500536

Therefore, the lowest common multiple of 717,856,471,894 is 14357500536.

LCM Formula to Find Lowest Common Multiple of 717,856,471,894

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 856 x 471 x 894 = 258435009648

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

856 : 1, 2, 4, 8, 107, 214, 428, 856

471 : 1, 3, 157, 471

894 : 1, 2, 3, 6, 149, 298, 447, 894

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,856,471,894, is 1.

Now, the common factors can be found like this.

717:3x 239

856:2x 2x 2x 107

471:3x 157

894:2x 3x 149

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 258435009648/(1x18)

LCM = 258435009648/18

LCM = 14357500536

Thus, we can understand that the LCM of 717,856,471,894 is 14357500536.
