Given numbers are 521,109,316,545

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

The LCM of 521,109,316,545 is 89726620.

Find LCM of 521,109,316,545 with Prime Factorization

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

109 x 521 x 1 x 316 x 5 = 89726620

Therefore, the lowest common multiple of 521,109,316,545 is 89726620.

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.

521 x 109 x 316 x 545 = 9780201580

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.

521 : 1, 521

109 : 1, 109

316 : 1, 2, 4, 79, 158, 316

545 : 1, 5, 109, 545

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,109,316,545, is 1.

Now, the common factors can be found like this.

521:521

109:109

316:2x 2x 79

545:5x 109

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

109 = 109

Therefore, the value for common factors is 109.

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 = 9780201580/(1x109)

LCM = 9780201580/109

LCM = 89726620

Thus, we can understand that the LCM of 521,109,316,545 is 89726620.
