Given numbers are 291,103,988,220

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

The LCM of 291,103,988,220 is 1628732820.

Find LCM of 291,103,988,220 with Prime Factorization

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

2 x 2 x 291 x 103 x 247 x 55 = 1628732820

Therefore, the lowest common multiple of 291,103,988,220 is 1628732820.

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.

291 x 103 x 988 x 220 = 6514931280

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.

291 : 1, 3, 97, 291

103 : 1, 103

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,103,988,220, is 1.

Now, the common factors can be found like this.

291:3x 97

103:103

988:2x 2x 13x 19

220:2x 2x 5x 11

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 = 6514931280/(1x4)

LCM = 6514931280/4

LCM = 1628732820

Thus, we can understand that the LCM of 291,103,988,220 is 1628732820.
