Calculate the LCM of 421,240,676,432

Given numbers are 421,240,676,432

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

The LCM of 421,240,676,432 is 153681840.

Find LCM of 421,240,676,432 with Prime Factorization


2 421, 240, 676, 432
2 421, 120, 338, 216
2 421, 60, 169, 108
2 421, 30, 169, 54
3 421, 15, 169, 27
421, 5, 169, 9

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

2 x 2 x 2 x 2 x 3 x 421 x 5 x 169 x 9 = 153681840

Therefore, the lowest common multiple of 421,240,676,432 is 153681840.

LCM Formula to Find Lowest Common Multiple of 421,240,676,432

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.

421 x 240 x 676 x 432 = 29506913280

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.

421 : 1, 421

240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,240,676,432, is 1.

Now, the common factors can be found like this.

421:421

240:2x 2x 2x 2x 3x 5

676:2x 2x 13x 13

432:2x 2x 2x 2x 3x 3x 3

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 2x 2x 2x 2x 3 = 192

Therefore, the value for common factors is 192.

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 = 29506913280/(1x192)

LCM = 29506913280/192

LCM = 153681840

Thus, we can understand that the LCM of 421,240,676,432 is 153681840.
