Given numbers are 431,146,744,621

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

The LCM of 431,146,744,621 is 4845553704.

Find LCM of 431,146,744,621 with Prime Factorization

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

2 x 3 x 431 x 73 x 124 x 207 = 4845553704

Therefore, the lowest common multiple of 431,146,744,621 is 4845553704.

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.

431 x 146 x 744 x 621 = 29073322224

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.

431 : 1, 431

146 : 1, 2, 73, 146

744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,146,744,621, is 1.

Now, the common factors can be found like this.

431:431

146:2x 73

744:2x 2x 2x 3x 31

621:3x 3x 3x 23

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 29073322224/(1x6)

LCM = 29073322224/6

LCM = 4845553704

Thus, we can understand that the LCM of 431,146,744,621 is 4845553704.
