Calculate the LCM of 423,419,786,228

Given numbers are 423,419,786,228

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

The LCM of 423,419,786,228 is 1764571572.

Find LCM of 423,419,786,228 with Prime Factorization


2 423, 419, 786, 228
3 423, 419, 393, 114
141, 419, 131, 38

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

2 x 3 x 141 x 419 x 131 x 38 = 1764571572

Therefore, the lowest common multiple of 423,419,786,228 is 1764571572.

LCM Formula to Find Lowest Common Multiple of 423,419,786,228

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.

423 x 419 x 786 x 228 = 31762288296

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.

423 : 1, 3, 9, 47, 141, 423

419 : 1, 419

786 : 1, 2, 3, 6, 131, 262, 393, 786

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,419,786,228, is 1.

Now, the common factors can be found like this.

423:3x 3x 47

419:419

786:2x 3x 131

228:2x 2x 3x 19

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 31762288296/(1x18)

LCM = 31762288296/18

LCM = 1764571572

Thus, we can understand that the LCM of 423,419,786,228 is 1764571572.
