Calculate the LCM of 550,644,710,203

Given numbers are 550,644,710,203

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

The LCM of 550,644,710,203 is 364648900.

Find LCM of 550,644,710,203 with Prime Factorization


2 550, 644, 710, 203
5 275, 322, 355, 203
7 55, 322, 71, 203
55, 46, 71, 29

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

2 x 5 x 7 x 55 x 46 x 71 x 29 = 364648900

Therefore, the lowest common multiple of 550,644,710,203 is 364648900.

LCM Formula to Find Lowest Common Multiple of 550,644,710,203

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.

550 x 644 x 710 x 203 = 51050846000

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.

550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

710 : 1, 2, 5, 10, 71, 142, 355, 710

203 : 1, 7, 29, 203

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 550,644,710,203, is 1.

Now, the common factors can be found like this.

550:2x 5x 5x 11

644:2x 2x 7x 23

710:2x 5x 71

203:7x 29

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 5x 7 = 140

Therefore, the value for common factors is 140.

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 = 51050846000/(1x140)

LCM = 51050846000/140

LCM = 364648900

Thus, we can understand that the LCM of 550,644,710,203 is 364648900.
