Given numbers are 553,406,254,440

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

The LCM of 553,406,254,440 is 896147560.

Find LCM of 553,406,254,440 with Prime Factorization

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

2 x 7 x 79 x 29 x 127 x 220 = 896147560

Therefore, the lowest common multiple of 553,406,254,440 is 896147560.

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 406 x 254 x 440 = 25092131680

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

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

254 : 1, 2, 127, 254

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 553,406,254,440, is 1.

Now, the common factors can be found like this.

553:7x 79

406:2x 7x 29

254:2x 127

440:2x 2x 2x 5x 11

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

2x 2x 7 = 28

Therefore, the value for common factors is 28.

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 = 25092131680/(1x28)

LCM = 25092131680/28

LCM = 896147560

Thus, we can understand that the LCM of 553,406,254,440 is 896147560.
