Calculate the LCM of 488,915,748,919

Given numbers are 488,915,748,919

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

The LCM of 488,915,748,919 is 1257963960.

Find LCM of 488,915,748,919 with Prime Factorization


2 488, 915, 748, 919
2 244, 915, 374, 919
61 122, 915, 187, 919
2, 15, 187, 919

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

2 x 2 x 61 x 2 x 15 x 187 x 919 = 1257963960

Therefore, the lowest common multiple of 488,915,748,919 is 1257963960.

LCM Formula to Find Lowest Common Multiple of 488,915,748,919

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.

488 x 915 x 748 x 919 = 306943206240

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.

488 : 1, 2, 4, 8, 61, 122, 244, 488

915 : 1, 3, 5, 15, 61, 183, 305, 915

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

919 : 1, 919

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 488,915,748,919, is 1.

Now, the common factors can be found like this.

488:2x 2x 2x 61

915:3x 5x 61

748:2x 2x 11x 17

919:919

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

2x 2x 61 = 244

Therefore, the value for common factors is 244.

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 = 306943206240/(1x244)

LCM = 306943206240/244

LCM = 1257963960

Thus, we can understand that the LCM of 488,915,748,919 is 1257963960.
