Given numbers are 641,553,626,626

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

The LCM of 641,553,626,626 is 221900098.

Find LCM of 641,553,626,626 with Prime Factorization

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

2 x 313 x 641 x 553 x 1 x 1 = 221900098

Therefore, the lowest common multiple of 641,553,626,626 is 221900098.

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.

641 x 553 x 626 x 626 = 138909461348

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.

641 : 1, 641

553 : 1, 7, 79, 553

626 : 1, 2, 313, 626

626 : 1, 2, 313, 626

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,553,626,626, is 1.

Now, the common factors can be found like this.

641:641

553:7x 79

626:2x 313

626:2x 313

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

2x 313 = 626

Therefore, the value for common factors is 626.

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 = 138909461348/(1x626)

LCM = 138909461348/626

LCM = 221900098

Thus, we can understand that the LCM of 641,553,626,626 is 221900098.
