Calculate the LCM of 100,253,220,455

Given numbers are 100,253,220,455

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

The LCM of 100,253,220,455 is 2302300.

Find LCM of 100,253,220,455 with Prime Factorization


2 100, 253, 220, 455
2 50, 253, 110, 455
5 25, 253, 55, 455
11 5, 253, 11, 91
5, 23, 1, 91

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

2 x 2 x 5 x 11 x 5 x 23 x 1 x 91 = 2302300

Therefore, the lowest common multiple of 100,253,220,455 is 2302300.

LCM Formula to Find Lowest Common Multiple of 100,253,220,455

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.

100 x 253 x 220 x 455 = 2532530000

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.

100 : 1, 2, 4, 5, 10, 20, 25, 50, 100

253 : 1, 11, 23, 253

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 100,253,220,455, is 1.

Now, the common factors can be found like this.

100:2x 2x 5x 5

253:11x 23

220:2x 2x 5x 11

455:5x 7x 13

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 5x 5x 11 = 1100

Therefore, the value for common factors is 1100.

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 = 2532530000/(1x1100)

LCM = 2532530000/1100

LCM = 2302300

Thus, we can understand that the LCM of 100,253,220,455 is 2302300.
