Calculate the LCM of 661,654,354,448

Given numbers are 661,654,354,448

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

The LCM of 661,654,354,448 is 5713197504.

Find LCM of 661,654,354,448 with Prime Factorization


2 661, 654, 354, 448
3 661, 327, 177, 224
661, 109, 59, 224

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

2 x 3 x 661 x 109 x 59 x 224 = 5713197504

Therefore, the lowest common multiple of 661,654,354,448 is 5713197504.

LCM Formula to Find Lowest Common Multiple of 661,654,354,448

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.

661 x 654 x 354 x 448 = 68558370048

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.

661 : 1, 661

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

354 : 1, 2, 3, 6, 59, 118, 177, 354

448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,654,354,448, is 1.

Now, the common factors can be found like this.

661:661

654:2x 3x 109

354:2x 3x 59

448:2x 2x 2x 2x 2x 2x 7

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 3 = 12

Therefore, the value for common factors is 12.

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 = 68558370048/(1x12)

LCM = 68558370048/12

LCM = 5713197504

Thus, we can understand that the LCM of 661,654,354,448 is 5713197504.
