Given numbers are 672,750,621,670,557

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

The LCM of 672,750,621,670,557 is 648902772000.

Find LCM of 672,750,621,670,557 with Prime Factorization

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

2 x 3 x 5 x 112 x 25 x 207 x 67 x 557 = 648902772000

Therefore, the lowest common multiple of 672,750,621,670,557 is 648902772000.

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.

672 x 750 x 621 x 670 x 557 = 116802498960000

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.

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750

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

670 : 1, 2, 5, 10, 67, 134, 335, 670

557 : 1, 557

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,750,621,670,557, is 1.

Now, the common factors can be found like this.

672:2x 2x 2x 2x 2x 3x 7

750:2x 3x 5x 5x 5

621:3x 3x 3x 23

670:2x 5x 67

557:557

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 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 116802498960000/(1x180)

LCM = 116802498960000/180

LCM = 648902772000

Thus, we can understand that the LCM of 672,750,621,670,557 is 648902772000.
