Given numbers are 812,753,136,421

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

The LCM of 812,753,136,421 is 8752094904.

Find LCM of 812,753,136,421 with Prime Factorization

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

2 x 2 x 203 x 753 x 34 x 421 = 8752094904

Therefore, the lowest common multiple of 812,753,136,421 is 8752094904.

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.

812 x 753 x 136 x 421 = 35008379616

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.

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

753 : 1, 3, 251, 753

136 : 1, 2, 4, 8, 17, 34, 68, 136

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,753,136,421, is 1.

Now, the common factors can be found like this.

812:2x 2x 7x 29

753:3x 251

136:2x 2x 2x 17

421:421

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 35008379616/(1x4)

LCM = 35008379616/4

LCM = 8752094904

Thus, we can understand that the LCM of 812,753,136,421 is 8752094904.
