Given numbers are 674,969,220

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

The LCM of 674,969,220 is 71841660.

Find LCM of 674,969,220 with Prime Factorization

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

2 x 337 x 969 x 110 = 71841660

Therefore, the lowest common multiple of 674,969,220 is 71841660.

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.

674 x 969 x 220 = 143683320

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.

674 : 1, 2, 337, 674

969 : 1, 3, 17, 19, 51, 57, 323, 969

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 674,969,220, is 1.

Now, the common factors can be found like this.

674:2x 337

969:3x 17x 19

220:2x 2x 5x 11

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 = 143683320/(1x2)

LCM = 143683320/2

LCM = 71841660

Thus, we can understand that the LCM of 674,969,220 is 71841660.

Here are some samples of LCM of two or more Numbers calculations.
