Calculate the LCM of 738,402,516,891

Given numbers are 738,402,516,891

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

The LCM of 738,402,516,891 is 420983244.

Find LCM of 738,402,516,891 with Prime Factorization


2 738, 402, 516, 891
3 369, 201, 258, 891
3 123, 67, 86, 297
41, 67, 86, 99

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

2 x 3 x 3 x 41 x 67 x 86 x 99 = 420983244

Therefore, the lowest common multiple of 738,402,516,891 is 420983244.

LCM Formula to Find Lowest Common Multiple of 738,402,516,891

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.

738 x 402 x 516 x 891 = 136398571056

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.

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

402 : 1, 2, 3, 6, 67, 134, 201, 402

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 738,402,516,891, is 3.

Now, the common factors can be found like this.

738:2x 3x 3x 41

402:2x 3x 67

516:2x 2x 3x 43

891:3x 3x 3x 3x 11

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 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 136398571056/(3x108)

LCM = 136398571056/324

LCM = 420983244

Thus, we can understand that the LCM of 738,402,516,891 is 420983244.
