Given numbers are 620,553,722,451

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

The LCM of 620,553,722,451 is 55821379460.

Find LCM of 620,553,722,451 with Prime Factorization

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

2 x 310 x 553 x 361 x 451 = 55821379460

Therefore, the lowest common multiple of 620,553,722,451 is 55821379460.

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.

620 x 553 x 722 x 451 = 111642758920

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

553 : 1, 7, 79, 553

722 : 1, 2, 19, 38, 361, 722

451 : 1, 11, 41, 451

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,553,722,451, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

553:7x 79

722:2x 19x 19

451:11x 41

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 = 111642758920/(1x2)

LCM = 111642758920/2

LCM = 55821379460

Thus, we can understand that the LCM of 620,553,722,451 is 55821379460.
