Calculate the LCM of 743,656,629,438

Given numbers are 743,656,629,438

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

The LCM of 743,656,629,438 is 67140939408.

Find LCM of 743,656,629,438 with Prime Factorization


2 743, 656, 629, 438
743, 328, 629, 219

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

2 x 743 x 328 x 629 x 219 = 67140939408

Therefore, the lowest common multiple of 743,656,629,438 is 67140939408.

LCM Formula to Find Lowest Common Multiple of 743,656,629,438

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.

743 x 656 x 629 x 438 = 134281878816

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.

743 : 1, 743

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

629 : 1, 17, 37, 629

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,656,629,438, is 1.

Now, the common factors can be found like this.

743:743

656:2x 2x 2x 2x 41

629:17x 37

438:2x 3x 73

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 = 134281878816/(1x2)

LCM = 134281878816/2

LCM = 67140939408

Thus, we can understand that the LCM of 743,656,629,438 is 67140939408.
