Calculate the LCM of 417,642,247,495

Given numbers are 417,642,247,495

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

The LCM of 417,642,247,495 is 3636894690.

Find LCM of 417,642,247,495 with Prime Factorization


3 417, 642, 247, 495
139, 214, 247, 165

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

3 x 139 x 214 x 247 x 165 = 3636894690

Therefore, the lowest common multiple of 417,642,247,495 is 3636894690.

LCM Formula to Find Lowest Common Multiple of 417,642,247,495

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.

417 x 642 x 247 x 495 = 32732052210

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.

417 : 1, 3, 139, 417

642 : 1, 2, 3, 6, 107, 214, 321, 642

247 : 1, 13, 19, 247

495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,642,247,495, is 1.

Now, the common factors can be found like this.

417:3x 139

642:2x 3x 107

247:13x 19

495:3x 3x 5x 11

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 32732052210/(1x9)

LCM = 32732052210/9

LCM = 3636894690

Thus, we can understand that the LCM of 417,642,247,495 is 3636894690.
