Given numbers are 742,604,521,290

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

The LCM of 742,604,521,290 is 16928425780.

Find LCM of 742,604,521,290 with Prime Factorization

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

2 x 371 x 302 x 521 x 145 = 16928425780

Therefore, the lowest common multiple of 742,604,521,290 is 16928425780.

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.

742 x 604 x 521 x 290 = 67713703120

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.

742 : 1, 2, 7, 14, 53, 106, 371, 742

604 : 1, 2, 4, 151, 302, 604

521 : 1, 521

290 : 1, 2, 5, 10, 29, 58, 145, 290

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,604,521,290, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

604:2x 2x 151

521:521

290:2x 5x 29

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 67713703120/(1x4)

LCM = 67713703120/4

LCM = 16928425780

Thus, we can understand that the LCM of 742,604,521,290 is 16928425780.
