Calculate the LCM of 490,343,365,636

Given numbers are 490,343,365,636

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

The LCM of 490,343,365,636 is 79624020.

Find LCM of 490,343,365,636 with Prime Factorization


2 490, 343, 365, 636
5 245, 343, 365, 318
7 49, 343, 73, 318
7 7, 49, 73, 318
1, 7, 73, 318

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

2 x 5 x 7 x 7 x 1 x 7 x 73 x 318 = 79624020

Therefore, the lowest common multiple of 490,343,365,636 is 79624020.

LCM Formula to Find Lowest Common Multiple of 490,343,365,636

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.

490 x 343 x 365 x 636 = 39015769800

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.

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

343 : 1, 7, 49, 343

365 : 1, 5, 73, 365

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,343,365,636, is 1.

Now, the common factors can be found like this.

490:2x 5x 7x 7

343:7x 7x 7

365:5x 73

636:2x 2x 3x 53

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

2x 5x 7x 7 = 490

Therefore, the value for common factors is 490.

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 = 39015769800/(1x490)

LCM = 39015769800/490

LCM = 79624020

Thus, we can understand that the LCM of 490,343,365,636 is 79624020.
