Given numbers are 393,281,655,154

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

The LCM of 393,281,655,154 is 85033410.

Find LCM of 393,281,655,154 with Prime Factorization

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

131 x 3 x 281 x 5 x 154 = 85033410

Therefore, the lowest common multiple of 393,281,655,154 is 85033410.

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.

393 x 281 x 655 x 154 = 11139376710

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.

393 : 1, 3, 131, 393

281 : 1, 281

655 : 1, 5, 131, 655

154 : 1, 2, 7, 11, 14, 22, 77, 154

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,281,655,154, is 1.

Now, the common factors can be found like this.

393:3x 131

281:281

655:5x 131

154:2x 7x 11

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

131 = 131

Therefore, the value for common factors is 131.

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 = 11139376710/(1x131)

LCM = 11139376710/131

LCM = 85033410

Thus, we can understand that the LCM of 393,281,655,154 is 85033410.
