Given numbers are 409,836,679,931

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

The LCM of 409,836,679,931 is 1625164772.

Find LCM of 409,836,679,931 with Prime Factorization

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

7 x 19 x 409 x 44 x 97 x 7 = 1625164772

Therefore, the lowest common multiple of 409,836,679,931 is 1625164772.

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.

409 x 836 x 679 x 931 = 216146914676

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.

409 : 1, 409

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

679 : 1, 7, 97, 679

931 : 1, 7, 19, 49, 133, 931

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,836,679,931, is 1.

Now, the common factors can be found like this.

409:409

836:2x 2x 11x 19

679:7x 97

931:7x 7x 19

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

7x 19 = 133

Therefore, the value for common factors is 133.

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 = 216146914676/(1x133)

LCM = 216146914676/133

LCM = 1625164772

Thus, we can understand that the LCM of 409,836,679,931 is 1625164772.
