Given numbers are 974,678,511,402,646

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

The LCM of 974,678,511,402,646 is 3651378720486.

Find LCM of 974,678,511,402,646 with Prime Factorization

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

2 x 3 x 487 x 113 x 511 x 67 x 323 = 3651378720486

Therefore, the lowest common multiple of 974,678,511,402,646 is 3651378720486.

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.

974 x 678 x 511 x 402 x 646 = 87633089291664

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.

974 : 1, 2, 487, 974

678 : 1, 2, 3, 6, 113, 226, 339, 678

511 : 1, 7, 73, 511

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

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,678,511,402,646, is 1.

Now, the common factors can be found like this.

974:2x 487

678:2x 3x 113

511:7x 73

402:2x 3x 67

646:2x 17x 19

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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 87633089291664/(1x24)

LCM = 87633089291664/24

LCM = 3651378720486

Thus, we can understand that the LCM of 974,678,511,402,646 is 3651378720486.
