Calculate the LCM of 137,840,743,638

Given numbers are 137,840,743,638

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

The LCM of 137,840,743,638 is 27275916360.

Find LCM of 137,840,743,638 with Prime Factorization


2 137, 840, 743, 638
137, 420, 743, 319

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

2 x 137 x 420 x 743 x 319 = 27275916360

Therefore, the lowest common multiple of 137,840,743,638 is 27275916360.

LCM Formula to Find Lowest Common Multiple of 137,840,743,638

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.

137 x 840 x 743 x 638 = 54551832720

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.

137 : 1, 137

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

743 : 1, 743

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 137,840,743,638, is 1.

Now, the common factors can be found like this.

137:137

840:2x 2x 2x 3x 5x 7

743:743

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 54551832720/(1x2)

LCM = 54551832720/2

LCM = 27275916360

Thus, we can understand that the LCM of 137,840,743,638 is 27275916360.
