Given numbers are 290,920,644,452

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

The LCM of 290,920,644,452 is 21103880.

Find LCM of 290,920,644,452 with Prime Factorization

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

2 x 2 x 5 x 23 x 29 x 2 x 7 x 113 = 21103880

Therefore, the lowest common multiple of 290,920,644,452 is 21103880.

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.

290 x 920 x 644 x 452 = 77662278400

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.

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

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

452 : 1, 2, 4, 113, 226, 452

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,920,644,452, is 2.

Now, the common factors can be found like this.

290:2x 5x 29

920:2x 2x 2x 5x 23

644:2x 2x 7x 23

452:2x 2x 113

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 2x 2x 5x 23 = 1840

Therefore, the value for common factors is 1840.

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 = 77662278400/(2x1840)

LCM = 77662278400/3680

LCM = 21103880

Thus, we can understand that the LCM of 290,920,644,452 is 21103880.
