Calculate the LCM of 655,644,356,739

Given numbers are 655,644,356,739

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

The LCM of 655,644,356,739 is 27743523220.

Find LCM of 655,644,356,739 with Prime Factorization


2 655, 644, 356, 739
2 655, 322, 178, 739
655, 161, 89, 739

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

2 x 2 x 655 x 161 x 89 x 739 = 27743523220

Therefore, the lowest common multiple of 655,644,356,739 is 27743523220.

LCM Formula to Find Lowest Common Multiple of 655,644,356,739

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.

655 x 644 x 356 x 739 = 110974092880

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.

655 : 1, 5, 131, 655

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

356 : 1, 2, 4, 89, 178, 356

739 : 1, 739

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,644,356,739, is 1.

Now, the common factors can be found like this.

655:5x 131

644:2x 2x 7x 23

356:2x 2x 89

739:739

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 = 110974092880/(1x4)

LCM = 110974092880/4

LCM = 27743523220

Thus, we can understand that the LCM of 655,644,356,739 is 27743523220.
