Calculate the LCM of 345,908,781,896

Given numbers are 345,908,781,896

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

The LCM of 345,908,781,896 is 54802957440.

Find LCM of 345,908,781,896 with Prime Factorization


2 345, 908, 781, 896
2 345, 454, 781, 448
345, 227, 781, 224

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

2 x 2 x 345 x 227 x 781 x 224 = 54802957440

Therefore, the lowest common multiple of 345,908,781,896 is 54802957440.

LCM Formula to Find Lowest Common Multiple of 345,908,781,896

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.

345 x 908 x 781 x 896 = 219211829760

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.

345 : 1, 3, 5, 15, 23, 69, 115, 345

908 : 1, 2, 4, 227, 454, 908

781 : 1, 11, 71, 781

896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,908,781,896, is 1.

Now, the common factors can be found like this.

345:3x 5x 23

908:2x 2x 227

781:11x 71

896:2x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 219211829760/(1x4)

LCM = 219211829760/4

LCM = 54802957440

Thus, we can understand that the LCM of 345,908,781,896 is 54802957440.
