Calculate the LCM of 746,815,670,938

Given numbers are 746,815,670,938

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

The LCM of 746,815,670,938 is 285147310.

Find LCM of 746,815,670,938 with Prime Factorization


2 746, 815, 670, 938
5 373, 815, 335, 469
67 373, 163, 67, 469
373, 163, 1, 7

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

2 x 5 x 67 x 373 x 163 x 1 x 7 = 285147310

Therefore, the lowest common multiple of 746,815,670,938 is 285147310.

LCM Formula to Find Lowest Common Multiple of 746,815,670,938

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.

746 x 815 x 670 x 938 = 382097395400

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.

746 : 1, 2, 373, 746

815 : 1, 5, 163, 815

670 : 1, 2, 5, 10, 67, 134, 335, 670

938 : 1, 2, 7, 14, 67, 134, 469, 938

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 746,815,670,938, is 1.

Now, the common factors can be found like this.

746:2x 373

815:5x 163

670:2x 5x 67

938:2x 7x 67

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 5x 67 = 1340

Therefore, the value for common factors is 1340.

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 = 382097395400/(1x1340)

LCM = 382097395400/1340

LCM = 285147310

Thus, we can understand that the LCM of 746,815,670,938 is 285147310.
