Given numbers are 438,343,838,619

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

The LCM of 438,343,838,619 is 38964840474.

Find LCM of 438,343,838,619 with Prime Factorization

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

2 x 219 x 343 x 419 x 619 = 38964840474

Therefore, the lowest common multiple of 438,343,838,619 is 38964840474.

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.

438 x 343 x 838 x 619 = 77929680948

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.

438 : 1, 2, 3, 6, 73, 146, 219, 438

343 : 1, 7, 49, 343

838 : 1, 2, 419, 838

619 : 1, 619

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,343,838,619, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

343:7x 7x 7

838:2x 419

619:619

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 = 77929680948/(1x2)

LCM = 77929680948/2

LCM = 38964840474

Thus, we can understand that the LCM of 438,343,838,619 is 38964840474.
