Given numbers are 646,713,622,977

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

The LCM of 646,713,622,977 is 139951320506.

Find LCM of 646,713,622,977 with Prime Factorization

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

2 x 323 x 713 x 311 x 977 = 139951320506

Therefore, the lowest common multiple of 646,713,622,977 is 139951320506.

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.

646 x 713 x 622 x 977 = 279902641012

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.

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

713 : 1, 23, 31, 713

622 : 1, 2, 311, 622

977 : 1, 977

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,713,622,977, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

713:23x 31

622:2x 311

977:977

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 = 279902641012/(1x2)

LCM = 279902641012/2

LCM = 139951320506

Thus, we can understand that the LCM of 646,713,622,977 is 139951320506.
