Calculate the LCM of 629,842,540,638

Given numbers are 629,842,540,638

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

The LCM of 629,842,540,638 is 45615998340.

Find LCM of 629,842,540,638 with Prime Factorization


2 629, 842, 540, 638
629, 421, 270, 319

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

2 x 629 x 421 x 270 x 319 = 45615998340

Therefore, the lowest common multiple of 629,842,540,638 is 45615998340.

LCM Formula to Find Lowest Common Multiple of 629,842,540,638

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.

629 x 842 x 540 x 638 = 182463993360

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.

629 : 1, 17, 37, 629

842 : 1, 2, 421, 842

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 629,842,540,638, is 1.

Now, the common factors can be found like this.

629:17x 37

842:2x 421

540:2x 2x 3x 3x 3x 5

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 2 = 4

Therefore, the value for common factors is 4.

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 = 182463993360/(1x4)

LCM = 182463993360/4

LCM = 45615998340

Thus, we can understand that the LCM of 629,842,540,638 is 45615998340.
