Calculate the LCM of 842,421,558,825

Given numbers are 842,421,558,825

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

The LCM of 842,421,558,825 is 64602450.

Find LCM of 842,421,558,825 with Prime Factorization


2 842, 421, 558, 825
3 421, 421, 279, 825
421 421, 421, 93, 275
1, 1, 93, 275

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

2 x 3 x 421 x 1 x 1 x 93 x 275 = 64602450

Therefore, the lowest common multiple of 842,421,558,825 is 64602450.

LCM Formula to Find Lowest Common Multiple of 842,421,558,825

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.

842 x 421 x 558 x 825 = 163185788700

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.

842 : 1, 2, 421, 842

421 : 1, 421

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,421,558,825, is 1.

Now, the common factors can be found like this.

842:2x 421

421:421

558:2x 3x 3x 31

825:3x 5x 5x 11

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 421 = 2526

Therefore, the value for common factors is 2526.

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 = 163185788700/(1x2526)

LCM = 163185788700/2526

LCM = 64602450

Thus, we can understand that the LCM of 842,421,558,825 is 64602450.
