Calculate the LCM of 448,667,781,946

Given numbers are 448,667,781,946

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

The LCM of 448,667,781,946 is 10035137728.

Find LCM of 448,667,781,946 with Prime Factorization


2 448, 667, 781, 946
11 224, 667, 781, 473
224, 667, 71, 43

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

2 x 11 x 224 x 667 x 71 x 43 = 10035137728

Therefore, the lowest common multiple of 448,667,781,946 is 10035137728.

LCM Formula to Find Lowest Common Multiple of 448,667,781,946

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.

448 x 667 x 781 x 946 = 220773030016

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.

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

667 : 1, 23, 29, 667

781 : 1, 11, 71, 781

946 : 1, 2, 11, 22, 43, 86, 473, 946

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 448,667,781,946, is 1.

Now, the common factors can be found like this.

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

667:23x 29

781:11x 71

946:2x 11x 43

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 220773030016/(1x22)

LCM = 220773030016/22

LCM = 10035137728

Thus, we can understand that the LCM of 448,667,781,946 is 10035137728.
