Calculate the LCM of 814,803,158,438

Given numbers are 814,803,158,438

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

The LCM of 814,803,158,438 is 14083014.

Find LCM of 814,803,158,438 with Prime Factorization


2 814, 803, 158, 438
11 407, 803, 79, 219
73 37, 73, 79, 219
37, 1, 79, 3

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

2 x 11 x 73 x 37 x 1 x 79 x 3 = 14083014

Therefore, the lowest common multiple of 814,803,158,438 is 14083014.

LCM Formula to Find Lowest Common Multiple of 814,803,158,438

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.

814 x 803 x 158 x 438 = 45234640968

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.

814 : 1, 2, 11, 22, 37, 74, 407, 814

803 : 1, 11, 73, 803

158 : 1, 2, 79, 158

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,803,158,438, is 1.

Now, the common factors can be found like this.

814:2x 11x 37

803:11x 73

158:2x 79

438:2x 3x 73

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 11x 73 = 3212

Therefore, the value for common factors is 3212.

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 = 45234640968/(1x3212)

LCM = 45234640968/3212

LCM = 14083014

Thus, we can understand that the LCM of 814,803,158,438 is 14083014.
