Calculate the LCM of 315,786,441,618

Given numbers are 315,786,441,618

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

The LCM of 315,786,441,618 is 59504130.

Find LCM of 315,786,441,618 with Prime Factorization


2 315, 786, 441, 618
3 315, 393, 441, 309
3 105, 131, 147, 103
7 35, 131, 49, 103
5, 131, 7, 103

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

2 x 3 x 3 x 7 x 5 x 131 x 7 x 103 = 59504130

Therefore, the lowest common multiple of 315,786,441,618 is 59504130.

LCM Formula to Find Lowest Common Multiple of 315,786,441,618

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.

315 x 786 x 441 x 618 = 67477683420

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.

315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315

786 : 1, 2, 3, 6, 131, 262, 393, 786

441 : 1, 3, 7, 9, 21, 49, 63, 147, 441

618 : 1, 2, 3, 6, 103, 206, 309, 618

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,786,441,618, is 3.

Now, the common factors can be found like this.

315:3x 3x 5x 7

786:2x 3x 131

441:3x 3x 7x 7

618:2x 3x 103

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 3x 3x 7 = 378

Therefore, the value for common factors is 378.

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 = 67477683420/(3x378)

LCM = 67477683420/1134

LCM = 59504130

Thus, we can understand that the LCM of 315,786,441,618 is 59504130.
