Calculate the LCM of 421,845,874,533

Given numbers are 421,845,874,533

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

The LCM of 421,845,874,533 is 12747766330.

Find LCM of 421,845,874,533 with Prime Factorization


13 421, 845, 874, 533
421, 65, 874, 41

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

13 x 421 x 65 x 874 x 41 = 12747766330

Therefore, the lowest common multiple of 421,845,874,533 is 12747766330.

LCM Formula to Find Lowest Common Multiple of 421,845,874,533

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 845 x 874 x 533 = 165720962290

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

845 : 1, 5, 13, 65, 169, 845

874 : 1, 2, 19, 23, 38, 46, 437, 874

533 : 1, 13, 41, 533

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,845,874,533, is 1.

Now, the common factors can be found like this.

421:421

845:5x 13x 13

874:2x 19x 23

533:13x 41

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

13 = 13

Therefore, the value for common factors is 13.

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 = 165720962290/(1x13)

LCM = 165720962290/13

LCM = 12747766330

Thus, we can understand that the LCM of 421,845,874,533 is 12747766330.
