Given numbers are 720,698,479,702

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

The LCM of 720,698,479,702 is 4694161680.

Find LCM of 720,698,479,702 with Prime Factorization

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

2 x 3 x 3 x 40 x 349 x 479 x 39 = 4694161680

Therefore, the lowest common multiple of 720,698,479,702 is 4694161680.

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.

720 x 698 x 479 x 702 = 168989820480

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.

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

698 : 1, 2, 349, 698

479 : 1, 479

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,698,479,702, is 1.

Now, the common factors can be found like this.

720:2x 2x 2x 2x 3x 3x 5

698:2x 349

479:479

702:2x 3x 3x 3x 13

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 168989820480/(1x36)

LCM = 168989820480/36

LCM = 4694161680

Thus, we can understand that the LCM of 720,698,479,702 is 4694161680.
