Calculate the LCM of 654,247,452,581

Given numbers are 654,247,452,581

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

The LCM of 654,247,452,581 is 21210908628.

Find LCM of 654,247,452,581 with Prime Factorization


2 654, 247, 452, 581
327, 247, 226, 581

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

2 x 327 x 247 x 226 x 581 = 21210908628

Therefore, the lowest common multiple of 654,247,452,581 is 21210908628.

LCM Formula to Find Lowest Common Multiple of 654,247,452,581

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.

654 x 247 x 452 x 581 = 42421817256

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.

654 : 1, 2, 3, 6, 109, 218, 327, 654

247 : 1, 13, 19, 247

452 : 1, 2, 4, 113, 226, 452

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,247,452,581, is 1.

Now, the common factors can be found like this.

654:2x 3x 109

247:13x 19

452:2x 2x 113

581:7x 83

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

2 = 2

Therefore, the value for common factors is 2.

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 = 42421817256/(1x2)

LCM = 42421817256/2

LCM = 21210908628

Thus, we can understand that the LCM of 654,247,452,581 is 21210908628.
