Calculate the LCM of 670,310,581,431

Given numbers are 670,310,581,431

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

The LCM of 670,310,581,431 is 5201036470.

Find LCM of 670,310,581,431 with Prime Factorization


2 670, 310, 581, 431
5 335, 155, 581, 431
67, 31, 581, 431

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

2 x 5 x 67 x 31 x 581 x 431 = 5201036470

Therefore, the lowest common multiple of 670,310,581,431 is 5201036470.

LCM Formula to Find Lowest Common Multiple of 670,310,581,431

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.

670 x 310 x 581 x 431 = 52010364700

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.

670 : 1, 2, 5, 10, 67, 134, 335, 670

310 : 1, 2, 5, 10, 31, 62, 155, 310

581 : 1, 7, 83, 581

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,310,581,431, is 1.

Now, the common factors can be found like this.

670:2x 5x 67

310:2x 5x 31

581:7x 83

431:431

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 52010364700/(1x10)

LCM = 52010364700/10

LCM = 5201036470

Thus, we can understand that the LCM of 670,310,581,431 is 5201036470.
