Calculate the LCM of 440,730,689,454

Given numbers are 440,730,689,454

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

The LCM of 440,730,689,454 is 5023664360.

Find LCM of 440,730,689,454 with Prime Factorization


2 440, 730, 689, 454
5 220, 365, 689, 227
44, 73, 689, 227

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

2 x 5 x 44 x 73 x 689 x 227 = 5023664360

Therefore, the lowest common multiple of 440,730,689,454 is 5023664360.

LCM Formula to Find Lowest Common Multiple of 440,730,689,454

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.

440 x 730 x 689 x 454 = 100473287200

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.

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

730 : 1, 2, 5, 10, 73, 146, 365, 730

689 : 1, 13, 53, 689

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,730,689,454, is 1.

Now, the common factors can be found like this.

440:2x 2x 2x 5x 11

730:2x 5x 73

689:13x 53

454:2x 227

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 5 = 20

Therefore, the value for common factors is 20.

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 = 100473287200/(1x20)

LCM = 100473287200/20

LCM = 5023664360

Thus, we can understand that the LCM of 440,730,689,454 is 5023664360.
