Calculate the LCM of 245,771,278,906

Given numbers are 245,771,278,906

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

The LCM of 245,771,278,906 is 7929434310.

Find LCM of 245,771,278,906 with Prime Factorization


2 245, 771, 278, 906
3 245, 771, 139, 453
245, 257, 139, 151

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

2 x 3 x 245 x 257 x 139 x 151 = 7929434310

Therefore, the lowest common multiple of 245,771,278,906 is 7929434310.

LCM Formula to Find Lowest Common Multiple of 245,771,278,906

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.

245 x 771 x 278 x 906 = 47576605860

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.

245 : 1, 5, 7, 35, 49, 245

771 : 1, 3, 257, 771

278 : 1, 2, 139, 278

906 : 1, 2, 3, 6, 151, 302, 453, 906

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 245,771,278,906, is 1.

Now, the common factors can be found like this.

245:5x 7x 7

771:3x 257

278:2x 139

906:2x 3x 151

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 47576605860/(1x6)

LCM = 47576605860/6

LCM = 7929434310

Thus, we can understand that the LCM of 245,771,278,906 is 7929434310.
