Calculate the LCM of 381,318,662,772,961

Given numbers are 381,318,662,772,961

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

The LCM of 381,318,662,772,961 is 4958719326636.

Find LCM of 381,318,662,772,961 with Prime Factorization


2 381, 318, 662, 772, 961
3 381, 159, 331, 386, 961
127, 53, 331, 386, 961

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

2 x 3 x 127 x 53 x 331 x 386 x 961 = 4958719326636

Therefore, the lowest common multiple of 381,318,662,772,961 is 4958719326636.

LCM Formula to Find Lowest Common Multiple of 381,318,662,772,961

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 318 x 662 x 772 x 961 = 59504631919632

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

318 : 1, 2, 3, 6, 53, 106, 159, 318

662 : 1, 2, 331, 662

772 : 1, 2, 4, 193, 386, 772

961 : 1, 31, 961

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,318,662,772,961, is 1.

Now, the common factors can be found like this.

381:3x 127

318:2x 3x 53

662:2x 331

772:2x 2x 193

961:31x 31

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 = 59504631919632/(1x12)

LCM = 59504631919632/12

LCM = 4958719326636

Thus, we can understand that the LCM of 381,318,662,772,961 is 4958719326636.
