Given numbers are 637,409,417,556

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

The LCM of 637,409,417,556 is 434569044.

Find LCM of 637,409,417,556 with Prime Factorization

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

139 x 637 x 409 x 3 x 4 = 434569044

Therefore, the lowest common multiple of 637,409,417,556 is 434569044.

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.

637 x 409 x 417 x 556 = 60405097116

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.

637 : 1, 7, 13, 49, 91, 637

409 : 1, 409

417 : 1, 3, 139, 417

556 : 1, 2, 4, 139, 278, 556

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,409,417,556, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

409:409

417:3x 139

556:2x 2x 139

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

139 = 139

Therefore, the value for common factors is 139.

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 = 60405097116/(1x139)

LCM = 60405097116/139

LCM = 434569044

Thus, we can understand that the LCM of 637,409,417,556 is 434569044.
