Given numbers are 480,421,721,682,670

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

The LCM of 480,421,721,682,670 is 3328800588960.

Find LCM of 480,421,721,682,670 with Prime Factorization

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

2 x 5 x 48 x 421 x 721 x 341 x 67 = 3328800588960

Therefore, the lowest common multiple of 480,421,721,682,670 is 3328800588960.

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.

480 x 421 x 721 x 682 x 670 = 66576011779200

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.

480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480

421 : 1, 421

721 : 1, 7, 103, 721

682 : 1, 2, 11, 22, 31, 62, 341, 682

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 480,421,721,682,670, is 1.

Now, the common factors can be found like this.

480:2x 2x 2x 2x 2x 3x 5

421:421

721:7x 103

682:2x 11x 31

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 5 = 20

Therefore, the value for common factors is 20.

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 = 66576011779200/(1x20)

LCM = 66576011779200/20

LCM = 3328800588960

Thus, we can understand that the LCM of 480,421,721,682,670 is 3328800588960.
