Given numbers are 515,641,674,970

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

The LCM of 515,641,674,970 is 21582258470.

Find LCM of 515,641,674,970 with Prime Factorization

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

2 x 5 x 103 x 641 x 337 x 97 = 21582258470

Therefore, the lowest common multiple of 515,641,674,970 is 21582258470.

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.

515 x 641 x 674 x 970 = 215822584700

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.

515 : 1, 5, 103, 515

641 : 1, 641

674 : 1, 2, 337, 674

970 : 1, 2, 5, 10, 97, 194, 485, 970

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,641,674,970, is 1.

Now, the common factors can be found like this.

515:5x 103

641:641

674:2x 337

970:2x 5x 97

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 = 215822584700/(1x10)

LCM = 215822584700/10

LCM = 21582258470

Thus, we can understand that the LCM of 515,641,674,970 is 21582258470.
