Calculate the LCM of 381,752,738,881

Given numbers are 381,752,738,881

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

The LCM of 381,752,738,881 is 31047299856.

Find LCM of 381,752,738,881 with Prime Factorization


2 381, 752, 738, 881
3 381, 376, 369, 881
127, 376, 123, 881

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

2 x 3 x 127 x 376 x 123 x 881 = 31047299856

Therefore, the lowest common multiple of 381,752,738,881 is 31047299856.

LCM Formula to Find Lowest Common Multiple of 381,752,738,881

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.

381 x 752 x 738 x 881 = 186283799136

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.

381 : 1, 3, 127, 381

752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

881 : 1, 881

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,752,738,881, is 1.

Now, the common factors can be found like this.

381:3x 127

752:2x 2x 2x 2x 47

738:2x 3x 3x 41

881:881

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 186283799136/(1x6)

LCM = 186283799136/6

LCM = 31047299856

Thus, we can understand that the LCM of 381,752,738,881 is 31047299856.
