Given numbers are 553,305,305,431

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

The LCM of 553,305,305,431 is 72694615.

Find LCM of 553,305,305,431 with Prime Factorization

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

5 x 61 x 553 x 1 x 1 x 431 = 72694615

Therefore, the lowest common multiple of 553,305,305,431 is 72694615.

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.

553 x 305 x 305 x 431 = 22171857575

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.

553 : 1, 7, 79, 553

305 : 1, 5, 61, 305

305 : 1, 5, 61, 305

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 553,305,305,431, is 1.

Now, the common factors can be found like this.

553:7x 79

305:5x 61

305:5x 61

431:431

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

5x 61 = 305

Therefore, the value for common factors is 305.

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 = 22171857575/(1x305)

LCM = 22171857575/305

LCM = 72694615

Thus, we can understand that the LCM of 553,305,305,431 is 72694615.
