Given numbers are 651,457,621,560

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

The LCM of 651,457,621,560 is 4926715920.

Find LCM of 651,457,621,560 with Prime Factorization

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

3 x 7 x 31 x 457 x 207 x 80 = 4926715920

Therefore, the lowest common multiple of 651,457,621,560 is 4926715920.

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.

651 x 457 x 621 x 560 = 103461034320

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.

651 : 1, 3, 7, 21, 31, 93, 217, 651

457 : 1, 457

621 : 1, 3, 9, 23, 27, 69, 207, 621

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,457,621,560, is 1.

Now, the common factors can be found like this.

651:3x 7x 31

457:457

621:3x 3x 3x 23

560:2x 2x 2x 2x 5x 7

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 103461034320/(1x21)

LCM = 103461034320/21

LCM = 4926715920

Thus, we can understand that the LCM of 651,457,621,560 is 4926715920.
