Calculate the LCM of 654,448,905,143

Given numbers are 654,448,905,143

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

The LCM of 654,448,905,143 is 18958779840.

Find LCM of 654,448,905,143 with Prime Factorization


2 654, 448, 905, 143
327, 224, 905, 143

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

2 x 327 x 224 x 905 x 143 = 18958779840

Therefore, the lowest common multiple of 654,448,905,143 is 18958779840.

LCM Formula to Find Lowest Common Multiple of 654,448,905,143

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 448 x 905 x 143 = 37917559680

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

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

905 : 1, 5, 181, 905

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,448,905,143, is 1.

Now, the common factors can be found like this.

654:2x 3x 109

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

905:5x 181

143:11x 13

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 = 37917559680/(1x2)

LCM = 37917559680/2

LCM = 18958779840

Thus, we can understand that the LCM of 654,448,905,143 is 18958779840.
