Given numbers are 976,283,686,643

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

The LCM of 976,283,686,643 is 60917398192.

Find LCM of 976,283,686,643 with Prime Factorization

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

2 x 488 x 283 x 343 x 643 = 60917398192

Therefore, the lowest common multiple of 976,283,686,643 is 60917398192.

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.

976 x 283 x 686 x 643 = 121834796384

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.

976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976

283 : 1, 283

686 : 1, 2, 7, 14, 49, 98, 343, 686

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 976,283,686,643, is 1.

Now, the common factors can be found like this.

976:2x 2x 2x 2x 61

283:283

686:2x 7x 7x 7

643:643

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 121834796384/(1x2)

LCM = 121834796384/2

LCM = 60917398192

Thus, we can understand that the LCM of 976,283,686,643 is 60917398192.
