Calculate the LCM of 124,348,802,638

Given numbers are 124,348,802,638

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

The LCM of 124,348,802,638 is 47585868.

Find LCM of 124,348,802,638 with Prime Factorization


2 124, 348, 802, 638
2 62, 174, 401, 319
29 31, 87, 401, 319
31, 3, 401, 11

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

2 x 2 x 29 x 31 x 3 x 401 x 11 = 47585868

Therefore, the lowest common multiple of 124,348,802,638 is 47585868.

LCM Formula to Find Lowest Common Multiple of 124,348,802,638

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.

124 x 348 x 802 x 638 = 22079842752

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.

124 : 1, 2, 4, 31, 62, 124

348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348

802 : 1, 2, 401, 802

638 : 1, 2, 11, 22, 29, 58, 319, 638

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 124,348,802,638, is 2.

Now, the common factors can be found like this.

124:2x 2x 31

348:2x 2x 3x 29

802:2x 401

638:2x 11x 29

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 2x 29 = 232

Therefore, the value for common factors is 232.

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 = 22079842752/(2x232)

LCM = 22079842752/464

LCM = 47585868

Thus, we can understand that the LCM of 124,348,802,638 is 47585868.
