Calculate the LCM of 438,934,807,656,745

Given numbers are 438,934,807,656,745

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

The LCM of 438,934,807,656,745 is 13445389490640.

Find LCM of 438,934,807,656,745 with Prime Factorization


2 438, 934, 807, 656, 745
3 219, 467, 807, 328, 745
73, 467, 269, 328, 745

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

2 x 3 x 73 x 467 x 269 x 328 x 745 = 13445389490640

Therefore, the lowest common multiple of 438,934,807,656,745 is 13445389490640.

LCM Formula to Find Lowest Common Multiple of 438,934,807,656,745

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.

438 x 934 x 807 x 656 x 745 = 161344673887680

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.

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

934 : 1, 2, 467, 934

807 : 1, 3, 269, 807

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

745 : 1, 5, 149, 745

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,934,807,656,745, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

934:2x 467

807:3x 269

656:2x 2x 2x 2x 41

745:5x 149

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 3 = 12

Therefore, the value for common factors is 12.

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 = 161344673887680/(1x12)

LCM = 161344673887680/12

LCM = 13445389490640

Thus, we can understand that the LCM of 438,934,807,656,745 is 13445389490640.
