Calculate the LCM of 155,285,428,263

Given numbers are 155,285,428,263

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

The LCM of 155,285,428,263 is 994502940.

Find LCM of 155,285,428,263 with Prime Factorization


5 155, 285, 428, 263
31, 57, 428, 263

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

5 x 31 x 57 x 428 x 263 = 994502940

Therefore, the lowest common multiple of 155,285,428,263 is 994502940.

LCM Formula to Find Lowest Common Multiple of 155,285,428,263

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 285 x 428 x 263 = 4972514700

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

285 : 1, 3, 5, 15, 19, 57, 95, 285

428 : 1, 2, 4, 107, 214, 428

263 : 1, 263

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,285,428,263, is 1.

Now, the common factors can be found like this.

155:5x 31

285:3x 5x 19

428:2x 2x 107

263:263

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

5 = 5

Therefore, the value for common factors is 5.

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 = 4972514700/(1x5)

LCM = 4972514700/5

LCM = 994502940

Thus, we can understand that the LCM of 155,285,428,263 is 994502940.
