Given numbers are 638,713,402,670

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

The LCM of 638,713,402,670 is 457168470.

Find LCM of 638,713,402,670 with Prime Factorization

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

2 x 67 x 319 x 713 x 3 x 5 = 457168470

Therefore, the lowest common multiple of 638,713,402,670 is 457168470.

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.

638 x 713 x 402 x 670 = 122521149960

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.

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

713 : 1, 23, 31, 713

402 : 1, 2, 3, 6, 67, 134, 201, 402

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,713,402,670, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

713:23x 31

402:2x 3x 67

670:2x 5x 67

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

2x 2x 67 = 268

Therefore, the value for common factors is 268.

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 = 122521149960/(1x268)

LCM = 122521149960/268

LCM = 457168470

Thus, we can understand that the LCM of 638,713,402,670 is 457168470.
