Given numbers are 434,381,428,354

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

The LCM of 434,381,428,354 is 2087759604.

Find LCM of 434,381,428,354 with Prime Factorization

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

2 x 3 x 217 x 127 x 214 x 59 = 2087759604

Therefore, the lowest common multiple of 434,381,428,354 is 2087759604.

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.

434 x 381 x 428 x 354 = 25053115248

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.

434 : 1, 2, 7, 14, 31, 62, 217, 434

381 : 1, 3, 127, 381

428 : 1, 2, 4, 107, 214, 428

354 : 1, 2, 3, 6, 59, 118, 177, 354

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 434,381,428,354, is 1.

Now, the common factors can be found like this.

434:2x 7x 31

381:3x 127

428:2x 2x 107

354:2x 3x 59

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 3 = 12

Therefore, the value for common factors is 12.

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 = 25053115248/(1x12)

LCM = 25053115248/12

LCM = 2087759604

Thus, we can understand that the LCM of 434,381,428,354 is 2087759604.
