Given numbers are 620,615,641,406

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

The LCM of 620,615,641,406 is 9923179980.

Find LCM of 620,615,641,406 with Prime Factorization

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

2 x 5 x 62 x 123 x 641 x 203 = 9923179980

Therefore, the lowest common multiple of 620,615,641,406 is 9923179980.

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.

620 x 615 x 641 x 406 = 99231799800

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

615 : 1, 3, 5, 15, 41, 123, 205, 615

641 : 1, 641

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,615,641,406, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

615:3x 5x 41

641:641

406:2x 7x 29

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 = 99231799800/(1x10)

LCM = 99231799800/10

LCM = 9923179980

Thus, we can understand that the LCM of 620,615,641,406 is 9923179980.
