Given numbers are 155,478,478

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

The LCM of 155,478,478 is 74090.

Find LCM of 155,478,478 with Prime Factorization

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

2 x 239 x 155 x 1 x 1 = 74090

Therefore, the lowest common multiple of 155,478,478 is 74090.

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.

155 x 478 x 478 = 35415020

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.

155 : 1, 5, 31, 155

478 : 1, 2, 239, 478

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,478,478, is 1.

Now, the common factors can be found like this.

155:5x 31

478:2x 239

478:2x 239

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

2x 239 = 478

Therefore, the value for common factors is 478.

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 = 35415020/(1x478)

LCM = 35415020/478

LCM = 74090

Thus, we can understand that the LCM of 155,478,478 is 74090.

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

• LCM of 479, 494, 472
