Given numbers are 578,454,421

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

The LCM of 578,454,421 is 55237726.

Find LCM of 578,454,421 with Prime Factorization

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

2 x 289 x 227 x 421 = 55237726

Therefore, the lowest common multiple of 578,454,421 is 55237726.

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.

578 x 454 x 421 = 110475452

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.

578 : 1, 2, 17, 34, 289, 578

454 : 1, 2, 227, 454

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,454,421, is 1.

Now, the common factors can be found like this.

578:2x 17x 17

454:2x 227

421:421

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

2 = 2

Therefore, the value for common factors is 2.

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 = 110475452/(1x2)

LCM = 110475452/2

LCM = 55237726

Thus, we can understand that the LCM of 578,454,421 is 55237726.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 217, 895, 629
• LCM of 326, 565, 209
• LCM of 703, 137, 719
